High Purity 99% Boron Nitride Ceramic Crucible BN Ceramic Grinding Pot PBN Ceramic Oil Cup for Vacuum Melting

High Purity 99% Boron Nitride Ceramic Crucible BN Ceramic Grinding Pot PBN Ceramic Oil Cup for Vacuum Melting

BN crystal structure there is no electrons in free,it is an insulator and have high melting point. Almost all of the molten metal were tested chemical reaction.

BN is thermostability, The operating temperature up to 2800??C in neutral or N2 .While the graphite operating temperature is far blew to the temperature of BN. The graphite will be produced carbonized under high temperature and high pressure.

The thermal conductivity of BN does not change with temperature and changes in theramal conductivity of graphite is relatively large.

Boron Nitride Ceramics are widely applied in automobile, electronic, electrical engineering, aerospace, scientific research, for extreme difficult environments such as electrical insulation, thermal insulation, high temperature resistance, chemical resistance, etc.
