What are the functions of boron nitride
The Boron Nitride Powder Overview Powder
Industrial-grade Boron nitride is pure white ceramic with hexagonal crystal structures similar to graphite. It can withstand temperatures that exceed 2,000°C. Depending on the grade, its dielectric power is close to 1000 volts/millimeter. The Boron Nitride is hot-pressed to shape of billets which can be readily processed into rods, plates, and even customized designs .
What are the purposes of the boron nitride?
1.Release agent for metal forming and lubricant to draw metal.
2.Special electrolysis and resistance compounds in high temperature states.
3.High-temperature solid lubricants,extrusion anti-wear additives,additives for the production of ceramic composite materials,refractory materials and antioxidant additives,especially in the case of corrosion resistance of molten metals,heat-enhanced additives,high-temperature insulation materials.
4.Heat-sealing desiccants for transistors and additives for polymers such as plastic resins.
5.Pressed into various shapes of boron nitride products,which can be used for high temperature, high pressure insulation, heat dissipation components.
6.Thermal materials for shielding in aerospace.
7.With the participation of catalysts,it can be converted into cubic boronnitride that is as hard like diamond after high temperature along with high pressure.
8.The structural materials of the Atomic Reactor.
9.Aircraft,rocket engine nozzle.
10.Insulator for high-voltage and high frequency electricity as well as plasma arc.
11.Packaging materials to block the radiation of neutrons.
12.The superhard materials created by an oxidation process called boronnitride can be transformed into high-speed tooling and drill bits for exploration of geology and oil drilling.
13.Separation ring for continuous casting steel, flow slot for the amorphous iron, release agents to allow continuous casting of aluminum(various various optical glass release substances)
14.Make all kinds of vessels to evaporate capacitor films, such as aluminum plating, picture tube aluminum plating aluminum plating, etc.
15.Various aluminum-plated packaging bags that are fresh, such as.
16.All kinds of laser anti-counterfeiting aluminum plating, brand hot-stamping materials, all kinds of cigarette and beer labels, packing box, packaging for cigarettes, etc.
17.The filler used in cosmetics for lipstick is non-toxic,lubricating and shiny.
As for optical applications due to the hardness that is high of C-BN's film and the excellent transmittance over the entire wavelength spectrum from ultraviolet(from about 200 nm)to far infrared,it is suitable as a coating on the surface of certain optical components. It is particularly suitable as a coating of window materials such as zinc selenide(ZnSe)and zinc sulfide(ZnS).In further, it exhibits excellent thermoshock resistance and hardness. It is predicted to become an appropriate window material high power detection and lasers.
