Boron Nitride Rod Description 

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. SAM's Boron Nitride rods are made from hot-pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance. Hexagonal boron nitride rods are particularly useful when the electrical conductivity of graphite would be a problem.
