Description of Boron Nitride Crucible

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 a high vacuum environment. SAM’s boron nitride crucibles are made from hot-pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similarly with graphite mechanically, but offers excellent electrical resistance.
