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. AEM’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.
