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 temperatures and maintain its lubricating capability in a high vacuum environment. ACM's Boron Nitride crucibles are made from hot-pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance.
