Hpbn Ceramic Components Hot Pressed Boron Nitride

Boron Nitride Ceramic Parts 

Boron Nitride ceramic are made by hot pressing hexagonal Boron Nitride powders. The color of BN products is milky, true density is 2.27g/cm , Mohs value is 2, they have a high melting point(sublimate point is 3000°C). When in a condition of inert atmosphere, their maximum service temperature can reach to 2800°C. Their thermal conductivity is 25W/(m·K), similar to stainless steel.And coefficient of liner  And coefficient of liner expansion is between 2.0×10 /°C to 6.5×10 /°C.
