This place is up for sale!

A now defunct ceramics manufacturing plant is available in China for any ceramics manufacturers looking to expand in the near future - the auction starts on April 14th! An old Lenox China ceramics manufacturing facility that includes the land as well as the facility and is estimated at around $11 million according to a pressofatlanticcity.com article which also states that the minimum bid for the property is $2.75 million. So, if you have the dough in hand, now is the time to ask yourself, "Are we ready to expand internationally?" Here are some notes from the article:

Lenox China produced ceramics and its renowned china at the plant starting in 1953. The factory was shuttered about five years ago, shortly after Department 56, a Minnesota-based ceramics and collectibles company, bought Lenox.

The plant is a 416,000-square-foot brick warehouse that includes 44,000 square feet of office space. From the outside, there are signs of deterioration, including dislodged bricks from the front steps.

This natural wear and tear should prevent any American-based ceramics manufacturing companies from making a decision on whether or not to buy this excellent piece of property. The time to strike for expansion is now, and with the ceramics engineering field on an upswing in the 21st century, this seems like a no-brainer for those who have the capital and the desire to reach a new market.

The Schedule for the Solar Meets Glass 2011 Conference

Equipment and service providers from across the glass and material sciences industry will be converging in Berlin, Germany in a few weeks to discuss the advancements made in our field regarding the advancement of photovoltaic cells. With the nations of the world beginning to realize that fossil fuels are more of a hindrance than a helping hand, it should come as no surprise that the leading manufacturers of energy technology are looking toward alternative forms of energy. And that is GOOD NEWS for those of us in the ceramics engineering fiels. A quote from www.solarpraxis.de discusses the colloquium:

The "Solar Meets Glass - 2nd Industry Summit for Quality, Logistics and Materials" brings the solar and glass industry together in order to discuss the current issues of both sectors. After a market and technology overview of photovoltaics and glass, the focus will be on the topics of quality, cost reduction and legistics.

According to the summit's main page, solar module manufacturers, equipment suppliers, automatic technology suppliers, solar system integrators, glass and ceramic manufacturers, investors, banks and analysts will all have something to gain from attending/monitoring this event. Regardless of what your role is in the ceramics engineering field, there is no doubt that a shift toward solar energy and the production of components of photovoltaic cells is on the rise. With the future of our industry so evident, it would be a poor decision to not follow the announcements that will come with this summit!

SunShot initiative is WinWin for Solar Component Manufacturers!

(Image Courtesy of treehugger.com)

The Secretary of Energy, Steven Chu, has recently announce a new government project that will make solar power a feasible alternative to fossil fuels in the near future. This program, rumored to cost around $30 million, will make photovoltaic cells more cost-effective and efficient than they are currently. This will allow more corporations and households to produce the majority of their own power using tax-deductible solar technology. So, for us in the ceramics engineering industry, this means there is a potential up-swing in many of the products that our industry produces that are instrumental in the development of photovoltaic cell technology. A recent article by treehugger.com editorializes,

$27 million in funding is a nice start, and it may sound like a lot - but if we truly want to produce 'moon shot' caliber results (ie, cheap, plentiful clean energy tech un under a decade), Obama's going to have to put his money where his mouth is.

While it is true that the government will need to "put up or shut up" as it were, in order to make the whole project meet its estimations, it's also true that the global ceramic manufacturing community can ultimately benefit from at least the suggestion of this future program. With the way the economic winds are blowing these days, it seems like investing in any component of solar technology is a logical choice; ceramics manufacturers can add this to many other aces in the hole as far as developing client relationships and determining global investment is concerned.

BGU Has News For You!

(Image Courtesy of paranormal.about.com)

An unstable form of Calcium may finally have been tamed by researchers at Ben-Gurion University of the Negev (BGU). With the goal of finding higher absorption and retention rates than other biological sources presently used for calcium supplements, researchers at BGU have succeeded - and it's all thanks to crustaceans. By using calcium carbonate, which is a huge component of many ceramics manufacturing processes, researchers have developed a way to reduce the chance for osteoporosis and poor blood-clotting in human beings. According to a recent article from azom.com,

"This type of Amorphous Calcium Carbonate (ACC) consists of unstable, nano-sized particles. Several species of crustaceans, including freshwater crayfish, are capable of stabilizing this mineral form so they can efficiently store and rapidly re-use large calcium quantities..."

Current results show that there is up to a forty percent reduction in absorption and retention rates in this compound versus current calcium sources. Based on this data, there may be a new and feasible source of calcium carbonate on the way in the near future. It will not only save lives, but also likely result in a decrease in costs for ceramics manufacturers across the world.

The annual Ceramic China expo is coming up again in May, and will be the home to professionals in the ceramic engineering and raw materials communities from across the globe from May 26th to May 29th. As we discussed in an earlier blog, China is currently running the rare earth metals scene, so it should come as no surprise that the country's upcoming expo will involve the top players in the ceramics manufacturing game, the latest news in the industry, and a lot of speculation. To help you wade through what is important versus what is ancillary, the Ceramics Engineering Blog has assembled some of the information that will be very relevant at the expo coming up in May.

According to PRLog.org, Ceramics China 2011 will include:

"Attendance [exceeding] 46,497 from 72 countries and regions in 2010... The total showspace of 67,000 square meters, 4,000 booths and 609 exhibitors from 16 countries including Italy, UK, Korea, Germany, Spain, Thailand, Brazil, Mainland China, Hong Kong & Taiwan..."

Ceramics engineers from across the globe will be converging on the China Import and Export Fair Complex in Guangzhou, China for three days of networking, discussion and debate regarding the future of materials processing not only in China, but across the globe. News regarding the expo and a brief itinerary are already available at the Ceramics China 2011 Expo website, and the venue is still open to all dedicated ceramics engineering professionals who wish to partake in the event, rub elbows with like-minded individuals and learn more about the rapidly-advancing world of ceramics manufacturing.

Yttrium-Stabilized Zirconia: A Mouthful at Mach Speed

(Image source: ceramics.org)

A paper published as an "Early View" article by the Journal of the American Society shows that yttrium-stablized zirconia can be sintered to full density in a matter of seconds at 850 degrees Celsius. The key is subjecting the process to a dc electrical field above the critical threshold. Traditional YSZ sintering would require hours at 1450 degrees Celsius. The paper was written by Marco Cologna, Rishi Raj and Boriana Rashkova, who are in the process of testing other materials that they hope to be able to report on to the ceramic manufacturing community soon. An article from ceramics.org covers the story. Here's an excerpt:

"The trio's technique was fairly straightforward. They made dog-biscuit shaped samples from 3 mol% nanograin YSZ. They then sintered samples in a vertical tubular furnace, applying a constant dc voltage, varying temperature and voltage. In the stages of their tests, they encountered a phenomenon I have written about before: accelerated sintering speeds at lower temperatures, dubbed field-assisted sintering or "FAST". In fact Raj, Di Yang and Hans Conrad had recently published another paper about how low (20 V/cm) dc electric dields could speed sintering and slow grain growth."

With many radical advances taking place in the field of ceramics engineering since the end of the century, it should come as no surprise that a leap-forward in sintering technology is nigh on the horizon. While the process has not been perfected yet, and the reports are only preliminary at this point, those in our industry would do well to look forward to a more detailed report coming from this team in the coming months.

Getting to Know your Magnets - The Design of Product Purity

(Image Source: Mark Weiss, thisoldhouse.com)

A recent special report from ceramicindustry.com discusses the importance of purity in a ceramics manufacturing process. It is likely that some contaminates, ferrous metals and others, may sometimes end up in a process where they have the potential to jeopardize the homogeny of a substance or damage machinery. As a result, the use of high-power magnetic separators must be employed to ensure the purity of your process. The article discusses the different types of magnets and metal detectors that can be employed and is a good read for anyone in the ceramics manufacturing industry. Here's an excerpt:

"Magnetic separators are classified as type A, B or C, in accordance with the type of magnetic circuit used. Processing lines are generally designated into the main areas (applications): primary, secondary and finishing. The size of the tramp metal to be removed determines whether a type A, B or C circuit is used. Type A is recommended for small fragments, while types B and C are recommended for larger tramp metals."

The article goes on to discuss the relationship between sensitivity and stability during the metal removal process, and explains precisely how these machines work. If you're in the ceramics manufacturing industry and you're not sure what the difference between these types of magnetic separators are, or are not sure how they work, the article is definitely a good read. In order to keep our products and processes free of unwanted contaminates, the use of metal detection and elimination is instrumental.

Growing Concerns Over Rare Earth Metals...

(Image Source: Missouri State University)

A recent article from the New York Times discusses the escalating problems that the United States and other nations of the world are having with maintaining a steady supply of rare earth metals. The article calls the situation a Chinese "hammerlock" that may sway the tides of import and export for several countries around the world for years to come. According to the article, 99 percent of two important elements: dysprosium and terbium come from China, who has recently put even tighter limits on the amount of these elements that can be exported, as China's own requirements for the elements has steadily increased over the last three years. The article explains it this way:

"In each of the last three years, China has reduced the amount of rare earths that can be exported. This year's export quotas are on track to be the smallest yet. But what is really starting to alarm Western governments and multinationals alike is the possibility that exports will be further restricted. Chinese officials will almost certainly be pressed to address the issue at a conference Thursday in Beijing. What they say could influence whether Australian regulators next week approve a deal by a Chinese company to acquire a majority stake in Australia's main rare-earth mine."

The article lists the commonly accepted price for the rare earth terbium at around 150$ pound on average. The reason that this information should alarm ceramics engineers is because we are in a constantly evolving industry. At some point, restrictions regarding materials will begin to affect us, whether it be restrictions with the number of chemicals we ourselves can export due to the global marketplace reaching a standstill or our inability to get a new element that it is discovered greatly benefits the ceramic industry. At one point, the idea of mixing diamonds with ceramic materials may have seemed silly, but today we have Diacer. It is likely that this international escalation will not stop with just terbium and dysprosium.

Biomaterialization and the New Vernacular...

(Image Source: www.azom.com)

Biomaterialization is a relatively new term in the scientific community, most notably used in areas regarding the production of inorganic materials based on the emulation of organic processes. The traditionally used term of 'biomineralization' is unsatisfactory, most notably because it refers to inorganic minerals being synthesized from biological micro- and nanostructures, when in reality they are inorganic materials that are derived from the mimicry of organic nanostructure processes. Recently, scientists from the University of Stuttgart have discovered a process by which they can produce oxide ceramics by biological means. A recent article from AZO materials discusses their progress:

"The scientists imitate the natural concept of biomineralization to produce non-metallic inorganic materials under environmental conditions. Organisms produce a bioorganic template to induce and control the formation of an inorganic phase (e.g. calcium carbonate) in an aqueous solution. This natural process offers promising perspectives for the synthesis of functional materials. Unfortunately, nature produces only minerals with minor technical importance. The interdisciplinary working group of Stuttgart University under participation of institutes of the faculties for chemistry as well as for energy technology, process engineering and biological engineering is working to overcome this issue."

For those in the ceramics manufacturing industry, the new terminology and the new process will be significant. As the article says, oxide ceramics such as titania, zinc oxide and zirconia are used in photovoltaic and fuel cells, and are in high demand due to their application as a scratch-resistant coating. With our industry constantly evolving, it's important for ceramics manufacturers to pay attention to new words like 'biomaterialization', as well as be aware of what they represent. This recent breakthrough serves as a shining example of how new developments may shape not only the future of materials sciences, but how we talk about ceramics engineering.

New Stipulations From The EPA On The Horizon...

The latest article from Chemical and Engineering News discusses a new proposal by the Environmental Protection Agency, which states that chemical manufacturers may have to provide reports regarding processing, productions and purpose for using their compounds every four years instead of five. Under the Toxic Substances Control Act, chemical makers must report twice yearly to the EPA in order to keep the TSCA Inventory updated. This has been the standard ever since the presidency of George W. Bush, when the EPA changed its time frame to the now recognized five year policy (Previously it was four years also). The article states:

“The proposed rule “will allow the agency to more effectively and expeditiously identify and address potential chemical risks and improve the information available to the public on chemicals most commonly used in commerce,” says Steve Owens, EPA assistant administrator for the Office of Chemical Safety & Pollution Prevention. The agency expects to finalize the changes by mid-2011.”

In addition to these new stipulations, this proposal would also require that companies that engineer chemicals make known in advance that the data that is supplied to the EPA is confidential business information, or it could potentially be placed in the public domain. This is likely the result of the EPA administrator, Lisa P. Jackson’s recent campaign to stop unnecessary trade secret claims from some members of the chemical industry. What this means for chemical manufacturers is that it looks like it’s back to the old way of doing things, so be prepared to modify your budgets.

New Ceramics Wrap Themselves in Blankets of Air to Ward Off Cold

At The Ceramic Engineering Blog, we've decided to continue our run of cold-themed posts (what with the heat wave and all it just seemed appropriate) by taking a look at a story that fell through the cracks for us this year. Back in March, NewScientist Magazine ran an article regarding a new technology developed by the Chinese Academy of Sciences and their colleagues which allows ceramics which endure extreme temperature changes to resist fracturing when moved from a high temperature environment to a low temperature, the scientists able to get the material to maintain its strength even when cooling from near-melting point temperatures of around 3,210 degrees Celsius. The article by NewScientist explains the process:

"They did this by roughening the surface with plasma etching and concentrated nitric and hydrofluoric acids. The surface ended up covered in nanoscale fin shapes, similar to the nanoscale patterning of a lotus leaf. Like those leaves, the roughened ceramic is strongly hydrophobic, or water repellant. This is what makes the material resistant to heat shock. It traps pockets of air at its roughened surface, so when cooled suddenly by dunking in water, or if the surrounding air temperature changes, the air pockets act as an insulating layer, buffering the bulk of the ceramic from the rapid change in temperature."

This new technology could potentially lead to a change in the types of materials used for applications which require thermally resistant, high-strength materials. Processes which usually use expensive metal alloys, such as those found within car engines, could be soon replaced by for efficient and less expensive ceramic materials. This could be an exciting prospect for the ceramics manufacturing industry, and is certainly something that those of us in the industry should keep an eye on.

Chilling Out: Ceramic Technologies from Natural Examples

(The Wilkins Ice Shelf. Source: twilightearth.com)

Sometimes the materials science industry can take a cue from mother nature and discover something that was previously untapped, yet right in front of our faces. A few years back, a group of scientists at Lawrence Berkeley National Laboratory used mother-of-pearl as a model for the creation of advanced ceramic materials. Mother-of-pearl, or "Nacre", is a naturally-occurring ceramic that is mostly found as reinforcement in mollusk shells. The team at Berkeley devised a way to emulate the structure of Nacre using the process of water freezing as a guide. An article from Chemical and Engineering News describes their process:

"The researchers knew that when saltwater freezes, it can form tiny plates of ice. Impurities in the water are squeezed out as the plates form and become trapped in the spaces between them. [The group at Berkeley] exploits this behavior using concentrated suspensions of ceramic particles in water. As the water freezes, it pushes the ceramic particles into the layers between the ice plates. The rate of freezing determines the thickness of the resulting ceramic layers, which can range from 1 to 200 µm."

The ice is then removed by the process of freeze-drying, leaving a ceramic scaffold behind with ice plate-shaped pores. After stabilization, the pores can be filled with a secondary compound (examples in the article include epoxy and aluminum alloy, but there are several options). John Halloran, a materials scientist at the University of Michigan described the results of the project as displaying "remarkably improved mechanical properties" compared to standard ceramics developed from today's processes. This discovery has several applications, including the possibility of devising bone substitutes that are four times stronger than the current industry standard.

The BBC Projects Big Things for North American Ceramics Market

(Image courtesy of BBC Research)

BBC has released a new technical market research report which suggests that by 2014, the North American high-performance ceramic coatings market will be worth an estimated $2 billion dollars, up from $1.4 billion in 2009. An article on the report from AZO Materials divides the market into segments, and then gives a rundown of how each segment is performing, along with an estimate on how these segments will continue to grow over the next three and a half years. The largest segment was identified as thermal spray coatings, which was worth an estimated $953 million in 2009, but is expected to reach $1.4 billion by 2014 (to put that into perspective, that is the entire market value of all segments in 2009). Of the second-largest segment, AZO had this to say:

"The second-largest segment, chemical vapor deposition, is estimated at $183 million in 2009, down from $213 million in 2008. It is expected, however, to increase by a 5-year CAGR (Compound Annual Growth Rate) of 3.8% to reach nearly $221 million in 2014. The physical vapor deposition segment (for comparison) is projected to have a 5-year CAGR of 7.4%, rising from $187 million in 2009 to nearly $267 million in 2014.

What this illustrates is that even segments of the market that were previously failing are picking up steam and should begin and continue to grow over the next five years. So, why the sudden boom in the ceramics manufacturing industry? New developments in materials science (Including innovations like DiaCer, see previous posts) and the invention of new processes with which to develop them have been emerging from the woodwork over the last few years. High-performance ceramic coatings is one of the few industries today that has been able to use innovation to overcome an otherwise bleak economical environment. Over the next three and a half years, those in the ceramics and materials science field can expect a lot of opportunities for continued growth and expansion.

China Begins New Export Restrictions on Rare Earth Deposits

(Graphic courtesy of "Rare Earth Elements--Critical Resources for High Technology," Gordon B. Haxel et al., U.S. Geological Survey, November 2002)

If you're in the ceramics manufacturing industry (and if you're not, I wonder what you come to this blog for, hopefully for my charming writing style) then you are aware that rare earth metals are instrumental in many advanced materials processes. Businessweek has recently predicted in an article that a resource dispute between China and the United States may be fast approaching. As is depicted by the graph above, in recent years China has been climbing the rankings of the nations with the most rare earth elements, and now that they are on par with and surpassing the United States, they have a very large bargaining chip when it comes to these deposits of rare elements.

China has opted to cut export quotas by 72 percent in the second half of 2010. This means that it's likely that the US will have a shortage of rare earth elements in the coming months, which could be potentially disastrous to our industry, and possibly the world economy as a whole. What this means for local ceramics manufacturers is that they'll need to modify their budgets to accommodate the extra prices on importation of these rare elements. According to an article on these new developments by Ceramic Tech Today "China's Ministry of Commerce says shipments for the second half of 2010 will be limited to 7,976 metric tons, less than half of the amount shipped in the first half of the year (16,304 metric tons)."

With all of the recent technological developments in ceramics and materials science, this news could not have come at a worse time. With the United States' economy not in tip-top shape and effecting the rest of the world, the limited resources of each country are becoming more and more important to global markets. The dispute that might occur could have far-reaching consequences throughout the entire world, and ceramics manufacturers everywhere should begin to consider re-estimating their costs and estimated production values.

Materials Science Schools Make BusinessWeek's Best Bargains List...

The Georgia Tech (which made number 2 in the list of twenty-five) logo featuring their mascot, Buzz

There's a lot of buzz (pun intended) regarding materials science schools as they relate to the amount a student invests into his or her higher education career versus what they get out of it after education. When highschool students are looking at where they want to go to begin their college career, one of the most influential statistics can be how big of a bargain the school is. No one wants to put a bunch of money into their education only to find out that their chosen field doesn't have the big pay-out they were expecting. For this reason, going to school for materials science may be one of the wisest investments a freshman in college can make.

An article from The American Ceramic Society sums up the information from the original BusinessWeek article as follows:

"The source data come from PayScale, a salary comparison and benchmarking service. Using this information, BusinessWeek calculated a 30-year net return on investment for more than 500 colleges and universities. According to the publication, these schools "boast a 30-year net return on investment that ranges from about $600,000 to more than $1.1 million, an improvement of 56 percent to 187 percent over the average for the entire sample. All of them sport decent graduation rates, too - in most cases, well above the 58 percent average."

With a potential overall return of more than a million dollars over the course of thirty years, it is evident that materials science is an industry that is rapidly growing. If you have a student looking to go into a science or engineering field, but they're not entirely certain what they want to do with their lives, you should probably mention the large amounts of money that people in the field are currently making. If you yourself are considering going back to school, or going for the first time, there is a lot to be said for the materials sciences, most notably the big payout.

iPad Apps for Materials Scientists

(Image courtesy of apple.com)

A recent article in the AZo Journal of Materials Online by Ian Birkby, cleverly titled "Don't Worry, Be App'y" suggests several iPad and iPhone Apps for Materials manufacturers that can assist them in their daily activities. While several of the apps that made the list can be really useful in the ceramics engineering field, many that Ian lists offer little or no assistance except for in incredibly rare scenarios. This article will separate the wheat from the chaff as far as these engineering apps go. The first app plugged is of course Azo's own materials app, which allows the user to find suppliers and equipment and stay on top of the latest materials news. Molecules and Periodic Lite are aimed toward the chemistry aspects of the materials design field, the former allowing the user to look at complex molecule strands in 3D while being able to rotate them at the touch of a finger, with the latter being a periodic table program which gives detailed information on every element.

Some of the apps suggested, like ConvertBot and the Scientific Calculator app are used primarily for the math aspect of the design process, being able to convert units of measurement and do complex mathematics. However, these apps can be useful to anyone in any engineering field. The other apps listed seem like they are merely filler, some of those suggested are later lampooned in the same article for being non-functional. Of the Metal Detector app, Ian writes:

"Well, let's start with the positives, the graphics certainly make it look like a metal detector and it really sounds like one, giving off that excellent 'Ive found a field full or roman coins" squawk, but, the metallic content of my forehead and the office carpet appeared to be quite high, so I'm sorry to say that you're going to need something a little more sophisticated to work out if you've an 18/8 stainless on the shelf."

The rest of the apps listed: Ceracoat, findNano, Skeptical Science and iAugment either have nothing to do with engineering, or are apps developed for related sciences that (it seems) were just added to the list for the sake of length. While there are about five apps listed in this article that could certainly help a materials engineer, almost half of them are totally irrelevant to the field. If you read the Azo journal and are interested in getting some of the apps they recommend, be careful that you're not paying for something that you will really never use.

Ceramics and Space: Keeping You Safe, Hundreds of Thousands of Miles From Home

A recent article for Materials Views by Martin Grolms discusses recent developments in ceramics technologies as it relates to thermal protection for space vehicles. While we have discussed the importance of ceramics in manned space exploration in previous posts, the material is becoming so essential to man's presence outside of our atmosphere that we believe it warrants a dedicated post. As pointed out in the article, some components of space vehicles may reach temperatures in excess of 2000 degrees Celsius, meaning that in order to keep our astronauts and their equipment safe, the highest durability of ceramics must be used:

The main concern in the design of ceramic laminates deals with the risk of decreasing the oxidation resistance. At the Polytechnic University of Turin, Italy, the effect on the oxidation behavior of porous and composite layers is investigated. To this purpose the microstructure and the main mechanical properties of different kinds of multilayer SiC (Silicon Carbide) are compared before and after oxidation.

The results of microscopy and several other exhaustive tests showed the presence of large pores in the composite laminate microstructure, which was not present in multilayer SiC. These pores greatly affect the mechanical behavior of components that are protected by a TPS (Thermal Protection System), which can mean the difference between the life and death of an astronaut or the loss of a multi-billion piece of technology. For these reasons it is evident why ceramics are so instrumental in our exploration of space.

Diamonds + Ceramics = One of the Most Advanced Substances on Earth

We've discussed this topic earlier, but now that confirmation is in and prizes are being

awarded, we've decided to fill in some of the details we left out last time. In Germany, a group of scientists have successfully combined the hardest substance known to man with high-tech ceramics to create a new material that is highly durable as well as having a relatively low value of friction. The project coordinator at the Fraunhofer Institute for Surface Engineering and Thin Films IST in Braunschweig, Dr. Lothar Schafer said that by using this recently developed process, they can apply a diamond layer of up to a half-square meter in size. Schafer was quoted as saying, "There's nothing else like it in the world. Ultimately, DiaCer is of interest for all components in machine construction that need strong resistance to wear."

DiaCer is one of the most advanced substances ever created by modern man, and its applications seem to extend to all levels of industry. Though the development and implementation of this new substance is still in its relative infancy, its designers have already been commended for their discovery with the Stifterverband Award for Science, which is awarded for scientific excellence in applied research projects carried out jointly by Fraunhofer Institutes and business enterprises and/or other research organizations.

The future could be very bright in the field of ceramics manufacturing. Currently, the heat shields on American space shuttles are made of highly advanced ceramics. Manufacturers who get on the ground floor with DiaCer might find themselves making new, advanced barriers for the next generation of manned space vehicles. If diamonds truly are forever, then DiaCer is easily the future of ceramics manufacturing.

New Zirconia Crowns May Replace The Metal Standard in Dentistry...

Recent developments in dental science suggest that the metal that oral surgeons have relied upon for decades for their crowns may be on the way out the door. A recent study sponsored by Noritake Dental Supply, Limited in Japan tested the durability of porcelain-fused-to-Zirconia (PFZ) versus the industry standard, porcelain-fused-to-metal (PFM). Durability tests were conducted from 2 months to 57 months and involved over two thousand patients and 22 dentists.

The study showed that after the mean survival time for posterior crowns (52 months), the probability for a PFZ crown to remain intact was 98.1%, where as the survival rate was only 95.8% for PFM crowns. This may not seem like a major difference, but ceramics manufacturers who specialize in Zirconia might see a boon to their businesses in the coming years as the Dental industry decides whether or not it will migrate to this new technology or stay with the PFM crowns that have served the profession for years.

The 22 practitioners were able to replicate these findings in different environments across three continents, and the results were the same regardless of oral location, whether molar or premolar. A total of 2,635 premolar and molar crowns were tested, and with the exception of the 1.9% of the PFZ crowns that failed, the results were almost unanimous: While the difference in the survival rate seems negligible, porcelain-fused-to-Zirconia crowns were superior to porcelain-fused-to-metal crowns. As medical technology continues to evolve, the demand for high-durability ceramics will continue to grow. Opportunities for expansion are on the horizon.
