Understanding the underlying mechanisms of rapid and energy-efficient flash sintering is key to tailoring the materials and processes to meet a wide range of performance requirements. Four recent articles in ACerS journals characterize and quantify some of these atomic-level phenomena.
Read MoreEven when a shape-memory ceramic’s lattice compatibility is improved, it still often experiences cracking after just a few dozen transformation cycles. Researchers at the Massachusetts Institute of Technology improved the cyclability of shape-memory zirconia ceramics with the help of a multimode modeling approach.
Read MoreRemoval of zirconia dental restorations is challenging and time consuming due to their high strength. Manufacturers offer diamond rotary instruments marketed specifically for removing zirconia restorations, but a new study reaffirmed that these instruments do not perform better or generate less heat than conventional ones.
Read MorePartially stabilized zirconia is commonly used in restorative dentistry because of its superior mechanical properties, but accurately measuring its fracture toughness can be challenging. Researchers now show focused ion beam milling may improve the accuracy of a particular measurement method.
Read MoreJülich scientists created yttria-coated transparent zirconia ceramics that demonstrated fracture toughness values far higher than tempered glass. Their method is suitable for industrial mass production.
Read MoreEileen loves caper movies and had high hopes for Ocean’s 8, the fourth episode in the heist genre that began with Ocean’s 11. She claims the movie’s takeaway message is that we need more ceramic engineers!
Read MoreResearchers at San Diego State University have developed a flash spark plasma sintering technique that can densify all kinds of materials, regardless of their electrical conductivity, in a matter of just seconds.
Read MoreResearchers at Jožef Stefan Institute (Ljubljana, Slovenia), the National Institute of Chemistry (Ljubljana, Slovenia), and Stockholm University (Stockholm, Sweden) have developed a new method to rapidly and evenly densify nanoceramics, offering incredible potential to save a lot of time and energy in sintering processes.
Read MoreA team led by researchers at the University of California, Davis has published new research showing that diffusion isn’t the only consideration when it comes to controlling grain growth.
Read MoreScientists at ITMO University in Russia recently developed a scalable method of printing europium-doped zirconia nanoparticles into beautifully glowing security holograms that could secure the authenticity of printed documents and more.
