What is Boron nitride?
Boron nitride is a crystal of nitrogen and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen, with four different variants: hexagonal boron nitride (HBN), rhomboidal boron nitride (RBN), cubic boron nitride (CBN) and wurtzite boron nitride (WBN). Boron nitride was invented more than 100 years ago and was first used as hexagonal boron nitride as a high-temperature lubricant. Its structure and properties are very similar to graphite. Boron nitride (BN) ceramics are compounds that were discovered as early as 1842. Foreign BN materials from the Second World War after a large number of research work, until 1955 to solve the BN hot pressing method was developed. The American Diamond Company and The United Carbon Company were the first to start production, producing more than 10 tons in 1960.
How is Boron nitride made?
In 1979, Sokolowski successfully used pulsed plasma technology to prepare cubic boron nitride (CBN) films at low temperature and low pressure. The equipment used is simple and the process is easy to realize, so it has developed rapidly.
Boron nitride application 
Boron nitride can be used as a release agent for metal forming and a lubricant for metal wire drawing, as well as resistance material. It can do high-temperature solid lubricant, extrusion anti-wear additives, production of ceramic composites additives, refractory materials and anti-oxidation additives, especially the occasion of anti-molten metal corrosion, heat reinforcement additives, high-temperature resistant insulation materials. It can be used as an additive in the manufacture of heat-sealing desiccants for transistors and polymers such as plastic resins.
At the same time, boron nitride can be pressed into various shapes of products, used for high temperature, high pressure, insulation, cooling parts. Boron nitride is also used as a thermal shield in aerospace. Boron nitride can be converted to diamond-hard cubic boron nitride by high temperature and pressure treatment with catalyst. Boron nitride is used in the structural materials of atomic reactors, in the vents of aircraft and rocket engines, and the insulators of high voltage, high-frequency electricity and plasma arcs. Superhard material made from boron nitride can be made into high-speed cutting tools and drill bits for geological exploration and oil drilling.
Boron nitride can be used in metallurgy for continuous casting steel separation ring, amorphous iron flow notch, continuous casting aluminum release agent (all kinds of optical glass film removal agent), all kinds of capacitor film aluminum plating, picture tube aluminum plating, display aluminum plating evaporation boat, all kinds of preservation aluminum plating bag. At the same time, boron nitride in cosmetics is used in lipstick filler, nontoxic and lubricious, and shiny. It can also be used as a variety of laser anti-counterfeiting aluminum plating, trademark bronzing materials, a variety of cigarette labels, beer labels, packaging boxes, cigarette packaging box aluminum plating and so on
