What are the functions of boron nitride

The Boron Nitride Powder Overview Powder

Industrial-grade Boron nitride is a pure white ceramic material with hexagonal crystal structures similar to graphite. It can withstand temperatures of up to 2,000 degrees Celsius, and depending on the grade, its dielectric strengths are close to 1000 volts/millimeter. Boron nitride is hot pressed in shapes of billets that can be processed into rods, bars,plates and even custom-designed shapes .

What's the roles of the boron nitride?

1.Release agents for the metal drawing and lubricant in metal drawing.

2.Special electrolysis and resistance substances in high temperature states.

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 to make transistors and add-ons for polymers like plastic resins.

5.Pressed into different designs of boron-nitride products. These can be used for heating, high-pressure, high temperature or heat dissipation parts.

6.Thermal shielding material in aerospace.

7.With the help of catalysts, it can be transformed into cubic boron nitride which is as strong as diamond following high temperature in addition to high pressure.

8.The structural materials of the nuclear reactor.

9.Aircraft,rocket engine nozzle.

10.Insulator for electric high-frequency and high voltage and plasma arches.

11.Packaging materials that block the radiation of neutrons.

12.The superhard material produced by an oxidation process called boronnitride is able to be used as high-speed tooling and drill bits that are used for geological exploration and drilling oil.

13.Separation ring for continuous cast steel in metallurgy. Also, flow slot for amorphous iron, release agent on continuous cast aluminum(various different optical glass release agents)

14.Make all kinds of evaporation boat for capacitor film aluminum plating, picture tube aluminum plating aluminum plating, etc.

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

16.All kinds of lasers used for anti-counterfeiting Aluminum plating, brand hot stampeding materials, all kinds of cigarette labels,beer labels,packaging boxes,cigarette packaging boxes,etc.

17.The filler used in cosmetics for lipstick is non-toxic,lubricating and shiny.

As for optical applications due to the high hardness of the cBN film and its high transmittance across the entire wavelength range from ultraviolet(from approximately 200 nm)to far infrared, it is suitable as a coating on the surface of some optical components, and is particularly suitable as a coating of window materials like zinc selenide(ZnSe)and zinc sulfide(ZnS).In further, it exhibits excellent resistance to thermal shocks and is extremely hard. It is expected to become the ideal material to use as a window for high power devices and optical lasers.
