Industrial Hot Pressed HBN Boron Nitride Spray Advantages:
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.
The life of BN crucible is far greater than the graphite crucible.

Industrial Hot Pressed HBN Boron Nitride Spray Usage:
high-performance material processing environment.
