Boron nitride This crystal is made up of atoms of boron and nitrogen. Its chemical makeup is 43.6% Boron and 56.4% Nitrogen. Boron nitride is available in four different forms: hexagonal boron nitride, diamond Square Boron Nitride, Cubic Boron Nitride and Wurtzite Boron Nitride.

Boron Nitride Properties

Boron Nitride is resistant to corrosion by chemicals and inorganic acids. It is also not affected when exposed to water and other organic acids. The boron nitrogen bond is broken when alkali is heated to high concentrations. In the air, it starts to oxidize above 1200degC. Boron Nitride is slightly soluble when heated in acid, but insoluble with cold water. It has a density relative of 2.25.

Most properties of boron materials are superior. The following properties are found in hexagonal boron Nitride: Low friction coefficient; good high temperature stability; good thermal shock resistance; high strength; high thermal conductivity.

Boron Nitride Applications

1. Hexagonal Borosidride is chemically stable and will not affect or wet most metals like steel, stainless, al, Fe, Ge, Bi, Si, etc. The boron-nitride material can be used in crucibles for metal melting, boats, liquid-metal delivery pipes, rockets nozzles, high power device bases and as electrical insulation.

2. Heat and corrosion resistant components can be manufactured using hexagonal Boron Nitride. These include high-temperature parts, rocket combustion chambers linings. It can be produced.

3. The hexagonal boron is widely used as an insulator for high-voltage and higher-frequency plasma arcs. Also, insulators are used as heating pipe sleeves as well high-frequency insulation and heat dissipation, and in high-voltage electric furnaces.

4. In the electronic industry, it’s used as an crucible for preparing gallium arsenide and gallium phosphide. It can also be used for heat sinks in semiconductor package heat sinks.

5. It is used to absorb neutrons and as a shielding material in atomic reactors. It can be used for infrared polarizers, infrared filters and optical paths in laser instruments.

6. Hexagonal boran nitride can be used to make a self-lubricating bearing. It is an excellent lubricant for high temperatures. Because boron is similar in many ways to graphite and has a number of physical properties, it’s called white graphite. It is used in conjunction with mica, talc silicates, fatty acids, and talc. They are collectively called white solids lubricants.

7. Boron Nitride can be used in various materials as an additive. Boron fiber is high modulus, high function fiber that has been processed with boron. It is a synthetic inorganic engineering material. It can be widely applied in the chemical industry and textile industry.
