Description of Boron Nitride Tube

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 similar to graphite mechanically, but it offers better electrical resistance. The Boron Nitride Tubes (BN Tubes) from Stanford Advanced Materials (SAM) are made from hot-pressed boron nitride blank.
