What is Boron Nitride?

Boron nitride (BN) is not as "famous" as other simple inorganic compounds such as sodium chloride or aluminum nitride. It is quite low-profile, 

but is often used in high-temperature applications due to its good thermal and chemical stability, and also has exciting application prospects in the field of nanotechnology.

Boron nitride (BN) is a material mainly made by synthetic means, consisting of only one boron atom to one nitrogen atom. It can have a variety of structural forms. 

Boron nitride is a heat-resistant, chemical-resistant and fire-resistant compound synthesized from boron and nitrogen. Boron nitride compounds are currently usually made by reacting boron trioxide or boric acid with ammonia or urea in a nitrogen atmosphere.

Hexagonal Boron Nitride

Hexagonal Boron Nitride (hBN) has optical properties that enable (nano)photonic functions. This form of boron nitride, similar to graphite, is the most stable and 

softest of the boron nitride polymorphs and is therefore used as a lubricant and additive in cosmetics. In addition to cosmetics, hexagonal boron nitride is also used in 

high-temperature ceramics, self-lubricating bearings and electronics.
