A Brief Overview of Boron Nitride Powder
Boron nitride industrial dust is pure white ceramic with an hexagonal crystal structure that is similar to graphite. It can withstand temperatures of more than 2,000 degC. Depending upon the grade, its dielectric strengths are around 1000 volts/mil. Boron nitride can be hot-pressed into it's form of billets, that can be processed into rods or plates and even customized shapes .
What is the roles of boron nitride?
1.Release chemical for metal drawing and lubricant for metal drawing.
2.Special electrolysis and resistance substances in 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 desiccants for transistors as well as 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 and heat dissipation materials.
6.Thermal shielding materials used in aerospace.
7.With the assistance of catalysts is possible to convert it into cubic boron nitride which is as strong as diamond following high temperature and high pressure treatment.
8.The elements that make up the structural components of the nuclear reactor.
9.Aircraft,rocket engine nozzle.
10.Insulator for electric high-frequency and high voltage and plasma arches.
11.Packaging substances to prevent neutron radiation.
12.The superhard substance created by the boron nitride procedure can be transformed into high-speed tooling and drill bits for exploration and drilling for oil.
13.Separation ring for continuous cast steel in metallurgy. Also, flow slot for an amorphous iron release agent designed for continuous cast aluminum(various Release agents using optical glasses)
14.Make any of the evaporation tanks for capacitor film aluminum plating, picture tube aluminum plating aluminum plating, etc.
15.Various aluminum-plated, fresh-keeping bags, etc.
16.All kinds of laser anti-counterfeiting aluminum plating, brand hot stamping material, all kinds of beer labels, cigarette labels, packaging box, packaging for cigarettes, etc.
17.The filler used in cosmetics for lipstick is non-toxic,lubricating and shiny.
In terms of optical application, due to the high hardness of the cBN film, and also the high transmittance across the entire length range from ultraviolet(from approximately 200 nm)to far-infrared, it can be used as a coating on the surface of some optical components, and is particularly suitable for Coating of window materials , such as zinc selenide(ZnSe)and zinc sulfide(ZnS).In the same way, it has excellent thermal shock resistance and hardness,and is expected to be the perfect window material suitable for high power optical components and lasers.
