Combat® Industrial Boron Nitride powders are pure, white, ceramic materials with a hexagonal crystal structure similar to graphite. Commonly known as “white graphite,” hexagonal BN (hBN) is a man-made ceramic produced by reacting boric acid or boron oxide and nitrogen at temperatures above 1600°C. The resulting product is a slippery white powder that has excellent high temperature stability (oxidation resistant up to 850°C) and lubricating properties.
