More info

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. SAM Boron Nitride break rings are made from hot pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similar with graphite mechanically, but offers excellent electrical resistance.
