BN Boron Nitride is often referred to as white graphite because it has a microstructure similar to that of graphite. However, unlike graphite, boron nitride is an excellent electrical insulator that has a higher oxidation temperature. It offers high thermal conductivity and good thermal shock resistance and can be easily machined to close tolerances in virtually any shape. After machining, it is ready for use without additional heat treating or firing operations. In inert and reducing atmospheres, BN will withstand temperatures over 2,000°C. It is commonly used as an insulator in contact with tungsten and graphite electrodes at those temperatures. All Boron Nitride grades can be used in oxidizing atmospheres up to 750°C. It is not wet by most molten metals and slags and can be used in contact with most molten metals including aluminum, sodium, lithium, silicon, boron, tin, germanium, and copper. Boron Nitride is available in a variety of solid grades, differentiated by binder and composite: BN-2000, BN-2300, BN-2800, BN-3000...
Hexagonal Boron Nitride has the same type of layer structure as graphite and provides a very good lubrication/mold-release characteristic. BN is stable up to approximately 2000°C in the inert atmosphere.Besides, Boron Nitride is stable against most organic solvents and corrosive chemicals, and unwettable by most molten metals and glasses. Boron Nitride has high electrical insulation and voltage resistance at high temperature and no changes in permittivity and dielectric loss up to high-frequency area. As for its lubricity and mold-release efficiency, friction coefficient of Boron Nitride does not change up to considerably high temperature in nitrogen atomosphere, which enables use up to approximately 950°C in the air. What's more, because of high thermal conductivity and high heat radiation, BN can be applied to various kind of heat radiators.
