Boron Nitride, also known as BN, Hexagonal boron nitride (H-BN) and hot pressed boron nitride, is a good self-lubricate ceramic that can withstand high temperature and maintain its lubricating capability in high vacuum environment. SAM Boron Nitride crucibles are made from hot pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similar with graphite mechanically, but offers excellent electrical resistance.
Hot pressed at high temperature (1900C).
Excellent corrosion resistance and thermal conductivity. Limited wear resistance
Self-bonded and high purity (>99%)
General purpose material
Bonded by boric oxide
Calcium borate bonded boron nitride
Enhanced moisture resitance
