Hexagonal Boron Nitride
 
Hexagonal boron nitride is the only boron nitride phase that exists in nature. It belongs to the hexagonal crystal system. It is white and has layered structure characteristics and lattice parameters similar to graphene, so it is also called white graphene. It has excellent high temperature resistance, thermal shock resistance, high temperature thermal stability, corrosion resistance and easy cutting processing comprehensive characteristics, and has broad application prospects in the fields of metallurgy, chemical industry, electronics and new energy.
 
Application of Hexagonal Boron Nitride
 
With the good high temperature resistance and electrical insulation of boron nitride products, it can be used as an electrical insulation material at high temperatures and has excellent thermal shock resistance.
 
Using its high thermal conductivity and penetration of microwave radiation, it can be used as a radar transmission window in the electronics industry.

 
Utilizing h-BN products with high melting point, low thermal expansion coefficient and stable performance to almost all molten metals, they can be used as high-temperature metal smelting crucibles, heat-resistant materials, heat sinks and thermal conductive materials.
 
Utilizing the excellent thermal stability of h-BN ceramics, it can be used under repeated rapid cooling and heating conditions from 1500°C to room temperature.
 
The use of h-BN ceramics has good corrosion resistance to acids, alkalis and glass slag, and is neither wetting nor reacting to most molten metals. It can be used as a crucible for smelting non-ferrous metals, precious metals and rare metals. Containers, pipes, pumps and other components.
 
The use of h-BN ceramics is not only a good heat conductor, but also an electrical insulator, which can be used as an ultra-high temperature insulating material.
 
The use of h-BN ceramics is transparent to microwaves and infrared, and can be used as a window that transmits infrared and microwaves, such as radar windows.
 
The use of h-BN ceramics has strong neutron absorption capacity, and can be mixed with various plastics and graphite in the atomic energy industry as a shielding material for atomic stacks.
 
The use of h-BN ceramics has high thermal stability, chemical stability and electrical insulation, and also has the characteristics of high thermal conductivity, good dielectric properties, and easy processing of products. It can be combined with TiB2 to prepare conductive ceramic evaporation boats.
 
The use of h-BN has stable performance under ultra-high pressure and can be used as a pressure transmission material and container.
 
Utilizing h-BN is the lightest ceramic material and can be used for high-temperature structural materials of aircraft and spacecraft.
 
Using the luminescence of h-BN, it can be used as an electroluminescent material.
