Boron nitride is a crystal composed of nitrogen atoms and boron atoms. The chemical formula is BN. The molecular weight is 24.84. The crystal structure of hexagonal boron nitride (HBN) powder is similar to that of graphite layer structure, showing loose, lubricated, easy moisture absorption, light weight and other properties of white powder. Its structure and performance are very similar to graphite, because of its excellent lubricity and wear resistance, commonly known as "white stone ink".
Hexagonal boron nitride has good electrical insulation, thermal conductivity, chemical stability; Theoretical density 2.29g/cm3, Mohs hardness 2, specific gravity 2.43, no obvious melting point, at 0.1MPA nitrogen at 3000℃ sublimation, in inert gas melting point 3000℃, in neutral reducing atmosphere, heat resistance to 2000℃, nitrogen and argon use temperature up to 2800℃, poor stability in oxygen atmosphere. The operating temperature is below 1000℃. Hexagonal boron nitride has the same expansion coefficient as quartz, but its thermal conductivity is ten times that of quartz.

Our company mainly produces high-end boron nitride powder products with special specifications. According to different customer needs, we can customize the production of hexagonal boron nitride powder products with high purity and high crystallity. At the same time, we can use advanced technology to produce nano-sized boron nitride powder with particle size less than 1 micron.

Field of Application

1. Because boron nitride has excellent lubricity and high temperature resistance, it is commonly used as high temperature solid lubricant, anti-wear additive for extruded profiles, release agent for metal molding and lubricant for metal wire drawing.

2, boron nitride has high temperature resistance, corrosion resistance, so it can be used for temperature resistance, refractory materials manufacturing, such as heat shielding materials required in aerospace, aircraft, rocket engine nozzle; Especially used to prevent molten metal corrosion related products of the main raw materials.

3, boron nitride has high insulation, so it can be used to make high voltage high frequency motor plasma arc insulator.

4. Boron nitride is non-toxic, lubricated, white, concealer strong, and glossy. Therefore, boron nitride is commonly used as filler for high-grade cosmetics, such as lipstick, foundation and so on.

5, the use of its high temperature resistance and insulation can be used to prepare special composite ceramics as the main raw material.
