Silicon nitride is a gray ceramic material with excellent thermal shock resistance and low wettability with molten metals. These properties make it ideal for harsh environment applications including automotive internal combustion engine parts and welding torch nozzles. The material's high abrasion resistance and mechanical strength make it suitable for bearing components, shafts, and semiconductor manufacturing equipment where clean environments are required.
