The difference of HBN and CBN

Boron nitride, chemical molecular formula is BN, is a crystal composed of nitrogen atoms and boron atoms. It has four different variants: Hexagonal boron nitride (H-BN), diamond-square boron nitride (R-BN), and Cube boron nitride (C-BN) and boron nitride of fibrous zinc ore.


1. Hexagonal boron nitride

Hexagonal boron nitride (H-BN), also known as "white graphene", is a single atom layer two-dimensional material alternated by nitrogen atoms and boronica. Graphene is similar, so it also has many properties that are similar to graphene.

Hexagonal boron nitride (H-BN) is a graphite lattice, which is loose, lubricated, easy to suck, light, light, difficulty, and high-temperature white powder. The Hexagonal boron nitride has no obvious melting point and has anti -chemical erosion properties. It does not respond to ordinary metals, rare earth metals, valuable metals, glass, and salt salt.

Hexagonal boron nitride is an excellent insulator with high thermal guidance, high antioxidant, high chemical, thermal stability and good mechanical properties. There are important applications such as layers.


2. Cube boron nitride

Cube boron nitride (C-BN) is an artificial synthetic material. Its hardness is second only to diamond. It belongs to super-hard materials and is synthesized by six-square boron nitrocide and catalyst under high temperature and high pressure.

Cube boron nitride has black, amber, and surface metallic colors. The size of the particles is usually below 1mm. It has high thermal stability and chemical inertia. Therefore, it is often used as a material for making ultra -hard tools.

Therefore, the main difference between six -way boron -nitride and cubic boron nitride is that the physical properties are different:

Hexagonal boron nitride is white, while the cubic boron nitride is mostly black, amber, etc.;
Hexagonal boron nitride is soft, while cubic boron nitride is very hard;
Hexagonal boron nitride can be used as raw materials to synthesize boron nitrite;
Hexagonal boron nitride is widely used. Cube boron nitride is generally used to make CBN knives.
