Silicon nitride, also named Si3N4, is a light grayish white color inorganic substance. It is a kind of synthetic refractory raw material with good wear resistance, high temperature resistance and corrosion resistance.
Properties of Silicon Nitride
- Low density
- High temperature strength
- Superior thermal shock resistance
- Excellent wear resistance
- Good fracture toughness
- Good oxidation resistance
- Low coefficient of thermal expansion and extremely high thermal shock resistance.
Application of Silicon Nitride
Because silicon nitride has corrosion resistance, high temperature resistance, and other characteristics, it is widely used in reciprocating engine components, bearings, metal processing, etc.
