What are the functions of boron nitride
Overview of Boron nitride Powder
Industrial-grade Boron nitride is a pure white ceramic material with the hexagonal structure of a crystal similar to graphite. The material can stand temperatures of more than 2,000 degC. Depending upon the grade, its dielectric strengths are close to 1000 volts/millimeter. The Boron Nitride is hot-pressed to its form as billets which are easily transformed into rods (bars), plates, rods and even customized shapes .
What are the main functions of Boron Nitride?
1.Release agent for metal forming and lubricant in metal drawing.
2.Special electrolysis and resistance compounds in high temperature state.
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 the addition of polymers to plastic resins.
5.Pressed into different shapes of boron nitride products,which are suitable for use as high temperature, high pressure insulation, heat dissipation materials.
6.Thermal materials for shielding in aerospace.
7.With the involvement of catalysts can be transformed into cubicboron nitride. It is as strong as diamond after high temperatures and pressure processing.
8.The components of the nuclear reactor.
9.Aircraft,rocket engine nozzle.
10.Insulator for High-frequency, high voltage electricity and plasma arches.
11.Packaging materials to prevent the radiation of neutrons.
12.The superhard material made by the boron nitride process can be transformed into high-speed cut tools, drill bits to be used for geological exploration and drilling for oil.
13.Separation of a ring to prevent continuous casting steel in metallurgy. anamorphous iron, release material used for cast continuous aluminum(various types of release agents made from optical glass)
14.Make all kinds of evaporation tanks for capacitor film aluminum plating,picture tube aluminum plating,display aluminum platingand more.
15.Various aluminum-plated bags for fresh-keeping, etc.
16.All kinds of lasers used for anti-counterfeiting aluminum plating, brand hot stamping material, all varieties of cigarette labeling, beer labels box, packaging for cigarettes, etc.
17.The filler used in cosmetics for lipstick is non-toxic,lubricating and shiny.
For optical applications, due because of the high hardness the cBN film, and also the high transmittance of the entire frequency range of ultraviolet(from approximately 200 nm)to far infrared. It is suitable as a coating on the surface of certain optical components. It is particularly suitable for use as a coating of window material such as zinc selenide(ZnSe)and zinc sulfide(ZnS).In out of that, it has good resistance to thermal shock and is hard, and is predicted to become one of the best window materials for high power detection and lasers.
