Introduction:
Silicon nitride has a strong covalent bond structure and has excellent comprehensive properties at -200ºC~1600ºC.
Features:
- High strength,
- High hardness
- High thermal conductivity,
- High temperature resistance,
- Wear and corrosion resistance, g
- Good fracture toughness,
- Excellent resistance to thermal shock and mechanical shock,
Application:
It is an excellent property that other metals or super alloys do not have, and it is known as the "excellent player" in the ceramic material industry.
