What is boron-nitride?
Boron Nitride crystal is part of the hexagonal crystal systems. Its structure and properties are similar to graphite.
Characteristics of Boron Nitride
It has excellent heat resistance, thermal stability and thermal conductivity. This makes it an ideal heat dissipation and high temperature insulation material. Boron Nitride is chemically stable, and it is resistant to corrosion from most molten metallics. It is also very self-lubricating. Boron nitride products can be machined up to 1/100mm accuracy and have a low hardness.

boron nitride
Boron nitride can also be used to make crucibles that melt semiconductors and high temperatures containers for metalurgical work, such as high-temperature containers, high-temperature parts for metallurgy, heat-dissipating semiconductor insulation parts, high temperature bearings, thermowells, and glass forming moulds.
Typically, boron Nitride is obtained in graphite-type structures, commonly called white graphite. Another type is called diamond type. Like the conversion of graphite into a diamond, graphite type boron is also possible to be made into diamond-type Boron Nitride at high temperatures (1800C) and high pressure (800Mpa). The boron-nitride’s B-N bond length (156pm), is comparable to that of diamond’s C/C bond length (154pm). It has the same density as diamond. It is similar in hardness to diamond and has better heat resistance than diamond. It is a superhard material that can withstand high temperatures and is ideal for cutting tools, drills, and abrasives.
Boron Nitride Structure
Boron nitride has a hexagonal crystal. This is usually a graphite-type boron nitride. However, there are also amorphous varieties. Other than the hexagonal crystal form of boron carbide, there are other crystal forms. Graphene-like 2D boron nitride crystallines have also been found (similarly to MoS:2D crystals).
