Description of Boron Nitride

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. The Boron Nitride Plates and Boron Nitride Sheets from Stanford Advanced Materials (SAM) are made from hot-pressed boron nitride blank.
