Hexagonal Boron Nitride Powder

Hexagonal Boron Nitride is a kind of synthetic material, which has a very similar hexagonal molecular structure With graphite. It is composed Of boron and nitrogen atoms from Boric Acid and Melamine which synthesis at very high temperatures. Since the high temperature, the finished powder has very high purity, its a nontoxic, safe material. Its unique properties of insulation, heat conduction, lubrication and high temperature resistanæ make it an almost multi application choice.

It is available in powder form in different particle sizes as 0.5 microns, 1.5 microns, 3microns, 5 microns, 10microns and 30 microns. It can also be customized as per the required particle size.

Characteristics of Hexagonal Boron Nitride (h-BN)

Physical properties of Hexagonal Boron Nitride (HBN)

The Boron Nitride can exist in different forms, depending on the arrangement of the boron and the nitrogen atoms. This gives rise to various bulk properties of boron nitride. The hexagonal form is the most stable and soft among the polymers. Therefore it is used as a lubricant and additive to cosmetic products.

Uses and Applications of Hexagonal Boron Nitride Powder
