Boron nitride powder is pure, white, ceramic material with lamellar structures similar to graphite.
Boron nitride is made up of nitrogen and boron atoms in the crystal, the crystal structure can be divided into: hexagonal boron nitride (HBN), dense rows of hexagonal boron nitride (WBN), the crystal structure of hexagonal boron nitride have similar graphite layer structure, loose, lubrication, easy absorption of moisture, light and other traits of white powder, say again so "white graphite. The theoretical density is 2.27g/cm3 and the Mohs hardness is 2.
Boron nitride is mainly used for refractory materials, semiconductor solid-phase doping sources, structural materials for atomic stacks, packaging materials for anti-neutron radiation, rocket engine constituent materials, high-temperature lubricants and mold release agents.
