Boron nitride can be used to manufacture crucibles for smelting semiconductors and high-temperature containers for metallurgy, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells and glass forming molds. The boron nitride usually produced has a graphite-type structure, commonly known as white graphite. The other is diamond type, similar to the principle of converting graphite to diamond, graphite type boron nitride can be converted into diamond type boron nitride at high temperature (1800°C) and high pressure (800Mpa). The BN bond length (156pm) of this type of boron nitride is similar to the CC bond length (154pm) of diamond, and the density is similar to that of diamond. Its hardness is comparable to that of diamond, and its heat resistance is better than that of diamond. It is a new type of high temperature resistance. The super-hard material is used to make drill bits, abrasive tools and cutting tools.
