Boron Nitride Aerosal Spray And Their Core Features
Boron Nitride Aerosal Spray | cdn11.bigcommerce.com
Boron nitride is a chemical compound with the chemical formula BN that contains an equal amount of boron and nitrogen atoms. BN can be found in a variety of crystalline forms because it is isoelectronic to a carbon lattice with a comparable structure. Because graphite's hexagonal form is the most stable and soft of the BN polymorphs, it is used as a lubricant and cosmetic component. The cubic or diamond-like variant is referred to as c-BN. Only diamond has a harder surface, but it is also more thermally and chemically stable. This is one of the primary reasons why it is included in Boron Nitride Aerosol Spray. The BN form of rare wurtzite is similar to lonsdaleite and may be harder than the cubic form.
The history of Boron nitride Aerosol Spray
Because boron nitride is not found in nature, it is synthesised from boric acid or boron trioxide. The initial product is amorphous BN powder, which is heated in nitrogen flow at temperatures above 1500 °C to convert to crystalline h-BN. To produce c-BN, h-BN powder is annealed at higher temperatures and pressures above 5 GPa. Unlike diamond, larger c-BN pellets can be made by fusing relatively inexpensive c-BN powders. As a result, c-BN has a wide range of mechanical engineering applications.
Low density, high thermal conductivity, low electrical conductivity, excellent temperature and lubrication stability, and the same crystal structure as graphite Cubic and wurtzite BN are now available. Wurtzite BN, which has a polycrystalline structure, is produced by detonation.
Hexagonal boron nitride suspension has a high heat conductivity. It contains no molten metals and can be applied to the protected surface immediately, even if it is already hot. It is inert to metals, glass, and molten salts, and it maintains its temperature at high temperatures.
This system is an excellent lubricant for hot parts and equipment due to its unique properties. It acts as a releasing agent as well as a coating for all extremely hot materials. Boron nitride is an excellent dry lubricant because it can withstand temperatures of up to 800°C in air and 1950°C in inert gas.
