Overview of Boron nitride Powder
The industrial powder Boron Nitride pure white ceramic with the same hexagonal crystal structure to graphite. Boron nitride is resistant to temperatures that exceed 2,000°C. Depending on the grade, its dielectric force is approximately 1000 volts/millimeter. The Boron nitride material is hot-pressed it's form of billets, that can easily be processed into rods, bars,plates and even custom designs .
What is the roles of boron nitride?
1.Release Agent for Metal forming and lubricant of metal drawing.
2.Special electrolysis as well as resistance materials in a high temperatures.
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 desiccant for transistors and other polymers that are additives, like plastic resins.
5.Pressed into various shapes of boron nitride products,which can be used as high temperature, high pressure insulation, heat dissipation pieces.
6.Thermal material shielding in aerospace.
7.With the aid of catalysts can be transformed into cubic boron nitride that is as hard as diamond , after high temperature in addition to high pressure.
8.The constituents 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 neutron radiation.
12.The superhard product of the boron nitride process can be made into high-speed Drill bits and cutting equipment used in geological exploration and oil drilling.
13.Separation band for continuous cast steel in metallurgy. Flow slot for the amorphous iron, release agents in continuous cast aluminum(various various optical glass release substances)
14.Make all sorts of Evaporation boats for capacitor films such as aluminum plating,picture tube aluminum plating,display aluminum plating, etc.
15.Various new-keeping aluminum-plated packaging bags.
16.All kinds of lasers, anti-counterfeiting aluminum plating, brand hot stamping materials, all kinds of beer labels, cigarette labels, packaging containers, boxes for cigarettes, etc.
17.The filler used in cosmetics for lipstick is non-toxic,lubricating and shiny.
In terms of optical applications,due to the high hardness of the c-BN film as well as the large transmittance throughout the frequency range of ultraviolet(from about 200 nm)to far infrared. This makes it suitable as a coating on the surface of certain optical components. It is especially suitable for the coating of window materials such as zinc selenide(ZnSe)and zinc sulfide(ZnS).In Additionally, it has high resistance to thermal shocks and is extremely hard. It is predicted to become one of the best window materials for high power light sources and detectors.
