Boron nitride powder

Basic information

Boron nitride powder is a crystal of nitrogen and boron atoms with four different variants: hexagonal boron nitride (H-BN), rhombic boron nitride (R-BN), cubic boron nitride (C-BN) and fibrinite boron nitride. The following mainly introduces two crystal structure products.

Uses of boron nitride

(1) Hexagonal boron nitride (H-BN) is a graphite lattice, which is loose, lubricating, easy to absorb moisture, light, insoluble and high temperature resistant white powder form. Hexagonal boron nitride has no obvious melting point and is resistant to chemical attack.

Hexagonal boron nitride is an excellent insulator with high thermal conductivity, high oxidation resistance, high chemical and thermal stability and good mechanical properties, and has important applications in composite material modification, sensors, field emitting devices, ultraviolet laser devices and antioxidant coatings.

(2) Cubic boron nitride (C-BN) is a synthetic material, its hardness is second only to diamond, belongs to superhard materials with high thermal stability and chemical inertness, so it is generally used as a material for manufacturing superhard tools.

The difference between hexagonal boron nitride and cubic boron nitride

The main difference lies in the different physical properties: hexagonal boron nitride is white, while cubic boron nitride is mostly black, amber, etc.; Hexagonal boron nitride is soft, while cubic boron nitride has high hardness; Hexagonal boron nitride can be used as a raw material to form cubic boron nitride; Hexagonal boron nitride has a wide range of uses, and cubic boron nitride is generally used to make CBN knives.
