Silicon nitride ceramic:

Silicon nitride and silicon nitride ceramics have outstanding high-temperature, mechanical, wear, and thermal properties. They also have moderate thermal conductivity, a low coefficient of thermal expansion, a moderately high elastic modulus, and unusually high fracture toughness for a ceramic.

Silicon nitride ceramic features:

1) Excellent wear resistance/hardness

2) Low thermal expansion

3) Good chemical corrosion resistance

4) High temperature performance

5) Good thermal shock behaviour

6) Good flexural strength

7) Low weight

8) High Stiffness

9) Electrically insulating
