Description

Boron nitride - represents material with unique properties which do it just irreplaceable in different industries, boron nitride is non-toxic, inert, does not interact with number of chemical reagents, and is also not moistened with many molten metals, etc.

Boron nitride is as fine electric and thermal insulator, thereby they is widely used in electronic instruments of special purpose.

The main purpose hexagonal (grafitopodobny, powder) boron nitride is synthesis of superhard materials: cubic and vyurtsitopodobny boron nitrides. Also boron nitride is widely applied as the dividing environment in the various processes (connected with metal, ceramics, glass, etc.), and as high-temperature lubricant.

Chemical formula: BN.

High-quality supersolid vyurtsitny boron nitride is used as starting material for the synthesis of polycrystals and the lezviyny tool working in the conditions of shock loadings.
