Silicon nitride ceramic plate substrate has low thermal expansion coefficient and high thermal conductivity, so it has excellent heat shock resistance. 

The hot-pressed sintered silicon nitride will not break after being heated to l000℃ and put into cold water.

Application:

1.Silicon nitride ceramic bearing

As a bearing material consideration, the most basic characteristic is rolling fatigue life, in order to evaluate the applicability of various ceramic bearings, 

the rolling life test with ceramic plate, the rolling life ranking results are: alumina< silicon carbide< zirconia< silicon nitride.

2.High-temperature parts of automotive engines.

3.Silicon nitride ceramic heat dissipation substrate.

4.Applications in other fields.

Silicon nitride ceramics can be used for chemical corrosion-resistant and wear-resistant parts and sealing rings due to their excellent high temperature resistance, corrosion resistance and other properties.
