Product Description
Boron Nitride, also known as BN, Hexagonal Boron Nitride (H-BN), and hot-pressed Boron Nitride, is an excellent self-lubricate ceramic that can withstand high temperatures 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.
