Boron Nitride is a material in which the extra electron of nitrogen (with respect to carbon) enables it to form structures that are isoelectronic with carbon allotropes. Also used in manufacture of alloys; in semiconductors, nuclear reactors, lubricants.
Hexagonal Boron Nitride can be used as an electrical insulator; as thermocouple protection sheaths, crucibles and linings for reaction vessels; and as a coating for refractory molds used in glass forming and in superplastic forming of titanium. It can also be incorporated in ceramics, alloys, resins, plastics, and rubber to give them self-lubricating properties. Hexagonal Boron Nitride is used the formulation of coatings and paints for high temperature applications. It is also used as a substrate for semi-conductors, lens coatings, and transparent windows.
Boron Nitride used in the manufacture of high-temperature equipment parts due to its excellent thermal and chemical stability. It is used as a lubricant and an additive to cosmetics, paints, dental cements and pencil leads.
It is also used to provide self lubricating properties to ceramics, alloys, resins, plastics and rubbers. In addition to this, it has many industrial applications such as xerographic process, laser printers, oxygen sensors and proton conductors. Cubic Boron Nitride is used as an abrasive material.
