Boron nitride is a crystal composed of nitrogen atoms and boron atoms. The crystal structure is divided into: hexagonal boron nitride (HBN), close-packed hexagonal boron nitride (WBN) and cubic boron nitride, among which the crystal of hexagonal boron nitride The structure has a similar graphite layered structure, and it is a white powder that is loose, lubricated, easy to absorb moisture, and light in weight, so it is also called "white graphite". Theoretical density is 2.27g/cm3, specific gravity: 2.43, Mohs hardness is 2. Hexagonal boron nitride has good electrical insulation, thermal conductivity, chemical stability, no obvious melting point, 3000 ℃ in 0.1MPA nitrogen, in In a non-reducing atmosphere, the heat resistance can reach 2000°C, and the use temperature can reach 2800°C in nitrogen and argon, and the stability is poor in an oxygen atmosphere, and the use temperature is below 1000°C. Hexagonal boron nitride has an expansion coefficient comparable to that of quartz, but a thermal conductivity ten times that of quartz.
Boron Nitride Properties
Hexagonal boron nitride (h-BN) performs very well under high heat condition and is effective in the air at temperatures of up to 900 degrees C, in the vacuum at 1,900 degrees C and in the inert environment at 2,000 degrees C. BN is self-lubricating as well, as a result, it does not need the use of molecules of gas or water stuck in its layers. Because of this, in a vacuum, which is important for aerospace applications, boron nitride (BN) can work perfectly.
