Boron Nitride Blank Description

Boron nitride blank is composed of high purity BN ceramics. 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. Hexagonal boron nitride (H-BN) behaves similarly with graphite mechanically, but offers excellent electrical resistance.
