Hexagonal boron nitride (h-BN) Powder
Pure Hexagonal Boron Nitride looks like talcum powder, white and dry lubricate. It is a synthetic material which although discovered in the early 19th century. hBN is synthetized by Melamine and Boric Acid in nitriding furnace.
Formula: BN, CAS No.: 10043-11-5, HS Code: 28500012.00
Hexagonal boron nitride (h-BN) is the equivalent in structure of graphite. Like graphite its plate like microstructure and layered lattice structure give it good lubricating properties.
