  • 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.
