Boron Nitride (BN) - Properties and Information on Boron Nitride

What is Boron Nitride
Boron Nitride is usually black, brown or dark red crystal, is sphalerite structure, has good thermal conductivity. The hardness is second only to diamond. It is a crystal of nitrogen and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen, with four different variants: hexagonal boron nitride (HBN), RBN, CBN and WURzite boron nitride (WBN).

Applications of Boron nitride
Boron nitride is an advanced synthetic ceramic material that can be used as powder, solid, liquid or aerosol. It has special temperature resistance, dielectric strength and thermal conductivity. Because of these different properties, boron nitride is an easily machined material. Boron nitride is an advanced synthetic ceramic material that can be used as powder, solid, liquid or aerosol. It has special temperature resistance, dielectric strength and thermal conductivity. Because of these different properties, boron nitride is an easily machined material. It can be used to make high-temperature components, rocket combustion chamber lining, thermal shielding for spacecraft, corrosion resistant parts for magneto-fluid generators and, in addition, it is not impregnated by most molten metals and slag and can therefore be used as a container for most molten metals, including aluminum, sodium, iron, steel, silicon, boron and copper. Dispersing boron nitride powder in oil or water can be used as a lubricant for drawing or pressing, or as a lubricant for sliding parts of high-temperature furnace. The sintered body of boron nitride can be used as a material for bearing and sliding parts with self-lubricating properties
