What are the functions of boron nitride
The Boron Nitride Powder Overview Powder
Industrial powder of Boron Nitride is pure white ceramic with hexagonal crystal structures similar to graphite. The material can stand temperatures as high as 2,000 degrees Celsius. Depending on the grade of the material, its dielectric strength could be approximately 1000 volts/millimeter. It is hot-pressed into shapes of billets which can be readily processed into rods (bars), plates, rods and even customized shapes .
What's the roles of boron nitride?
1.Release an agent to aid in metal forming and lubricant for metal drawing.
2.Special electrolysis and resistance materials in a high temperature conditions.
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 the addition of polymers to plastic resins.
5.Pressed into various designs of boron-nitride products. These are suitable for use as high temperature, high pressure insulation, heat dissipation parts.
6.Thermal material shielding in aerospace.
7.With the assistance of catalysts can be transformed to cubic boron, a nitride compound that is as strong as diamond following high temperature as well as high pressure treatments.
8.The components of the Atomic Reactor.
9.Aircraft,rocket engine nozzle.
10.Insulator for high-voltage and high-frequency electricity and plasma arches.
11.Packaging materials to stop neutron radiation.
12.The superhard substance created by the boron nitride process can be converted into high-speed cutters and drilling bits that are used for geological exploration and drilling oil.
13.Separation ring for continuous cast steel in metallurgy. It also has a flow slot to accommodate anamorphous iron, release material for continuous cast aluminum(various optical glass release agents)
14.Make all sorts of Evaporation vessels for capacitor film aluminum plating, picture tube aluminum plating aluminum plating.
15.Various aluminum-plated bags for fresh-keeping, etc.
16.All kinds of lasers for anti-counterfeiting metal plating, hot stamping brand materials, all kinds of beer labels and cigarette labels. box, packaging for cigarettes, etc.
17.The filler used in cosmetics for lipstick is non-toxic,lubricating and shiny.
With regard to optical applications, due to the high hardness of C-BN's film and the high transmittance across the entire band of wavelengths, from ultraviolet(from about 200 nm)to far infrared, it is suitable as a surface coating for certain optical components. It is particularly suitable as a coating of window materials like zinc selenide(ZnSe)and zinc sulfide(ZnS).In out of that, it has good heat shock resistance and toughness, and is anticipated to become the perfect window material suitable for high-power light sources and detectors.
