Hot pressure BN boron nitride ceramic sleeve

Boron nitride ceramic is particularly well suited as a burning bear material due to its high temperature resistance and its thermal cycling resistance. It does not react with many metals, ceramic rare earth, and other materials, and does not pollute the product. It does not crack in the hot and cold and hot environment. It can be used for sintering rare earth, ceramics and melting alloy, and also used in electron beam evaporation coating.


Advantages of Ceravite Plate

1. Excellent high temperatures resistance 

2. Excellent thermal cycling resistance

3. Low thermal expansion

4. Resists wetting by the vast majority of molten metals
