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 a high vacuum environment. Hexagonal boron nitride (H-BN) behaves similarly with graphite mechanically but offers excellent electrical resistance.
