Boron nitride This crystal is made up of nitrogen atoms, and boron. Its chemical formula is 56.4% boron, 43.6% of which is 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 soluble only in hot acid, and it is insoluble in cold. It has a density relative of 2.25.

Most properties of boron materials are better than those of carbon materials. 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; low expansion coefficient.

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, rocket nozzles, liquid metal delivery tubes, and other high-power devices.

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-nitride material is widely used for high-voltage, highfrequency, high temperature, high voltage insulation and heat dissipation, and highfrequency electric furnaces.

4. In the electronic industry, it’s used as an crucible for the production of gallium arsenide and gallium phosphide. It can also be used to heat 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, microwave filters, infrared filters and optical paths in laser instruments.

6. Hexagonal boran nitride can be used to make a self-lubricating bearing. It is also a good lubricant for high temperatures. Because boron is similar in many ways to graphite and has many physical properties, it’s called white graphite. It is used in conjunction with mica, talc silicates, fatty acids, and talc. They are collectively known as solid white 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 used in many industries, including the textile industry, aerospace, and chemical.
