What are the functions of boron nitride

Introduction to Boron Nitride Powder

The industrial powder Boron Nitride pure white ceramic with hexagonal crystals that are similar to graphite. The material can stand temperatures up to 2,000°C. And, depending on the grade, its dielectric strengths are around 1000 volts/millimeter. The Boron nitride material is hot-pressed its form as billets which can be readily processed into rods, bars,plates and even custom-designed designs .

What are the roles of boron nitride?

1.Release chemical for metal drawing as well as lubricant that is used to draw metal.

2.Special electrolysis and resistance materials 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 as well as additives to polymers such as plastic resins.

5.Pressed into various shapes of boron nitride products,which are suitable for use as high temperature, high pressure, insulation and heat dissipation elements.

6.Thermal shielding materials in aerospace.

7.With the involvement of catalysts can be converted into cubic boron-nitride, which is as hard as diamond after 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 , high-frequency and high-voltage electricity and plasma arc.

11.Packaging materials to prevent neutron radiation.

12.The superhard product of the process of boron Nitride is able to be used as high-speed drilling tools as well as cutting instruments that are used for geological exploration and oil drilling.

13.Separation rings for continuous casting steel in metallurgy,flow slot for anamorphous iron, release material on 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,display aluminum plating, etc.

15.Various fresh-keeping aluminum-plated packaging bags,etc.

16.All kinds and varieties of laser anti-counterfeiting aluminum plating, brand hot stamping material, all kinds of cigarette and beer labels, packing cases, boxes for packaging cigarettes.

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 the c-BN films and the high transmittance across the entire length range from 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 as Coating of window material such as zinc selenide(ZnSe)and zinc sulfide(ZnS).In the same way, it has excellent heat shock resistance and toughness, and is expected to become one of the best window materials for high power Lasers as well as detectors.
