Silicon Nitride (Si3N4)

Silicon Nitride (Si3N4) is a fully dense, high strength and high toughness ceramic material. It is used in numerous industrial applications, such as engine components, bearings and cutting tools.

Silicon Nitride has better high temperature capabilities than most metals combining retention of high strength and creep resistance with oxidation resistance. In addition, its low thermal expansion coefficient gives good thermal shock resistance compared with most ceramic materials.
