Within the body of a high-voltage multi-layer ceramic capacitor, a gap-type defect is beginning its career of destruction. The defect may be a void within the ceramic dielectric, a crack within the ...

There they are, seemingly beauties to behold. Ceramic pieces that have beautiful lines and patterns. The objects appear to be in perfect condition. But are they? Only a closer inspection will tell, ...

When high stress is applied to structural materials, catastrophic failure of the material occurs shortly after the initial defect forms due to stress concentration. It is highly desirable to develop a ...

The common engineering ceramic materials can be identified as Aluminium Oxide (Alumina), Silicon Carbide, Silicon Nitride, Sialon and Zirconia. These materials are classified as “Engineering” or ...

A new way to calculate the interaction between a metal and its alloying material could speed the hunt for a new material that combines the hardness of ceramic with the resilience of metal. A new way ...

Silicon carbide after irradiation, in which loose carbon atoms (green) move toward the boundary (dashed line) between grains of the crystalline ceramic. Courtesy: Hongliang Zhang Grain boundaries in ...
