What are the functions of boron nitride

Overview of Boron-Nitride Powder

Boron nitride industrial powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. Boron nitride can withstand temperatures that exceed 2,000°C. Depending on the grade, its dielectric force is approximately 1000 volts/mil. It is hot-pressed into forms of billets, that can easily be processed into rods, plates, or bars and even custom shapes .

What are the roles of boron nitride?

1.Release an agent to aid in metal forming and lubricant used for drawing of metal.

2.Special electrolysis and resistance materials 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 and add-ons for polymers like plastic resins.

5.Pressed into different shapes of boron nitride products,which can be used as high temperature, high pressure insulation, heat dissipation equipment.

6.Thermal shielding materials used in aerospace.

7.With the help of catalysts, it can be transformed into cubic boronnitride that is as hard as diamond after high temperatures as well as high pressure treatments.

8.The structural materials of the Atomic reactor.

9.Aircraft,rocket engine nozzle.

10.Insulator for the high-voltage and high frequency of electricity as well as plasma arches.

11.Packaging materials to block the radiation of neutrons.

12.The superhard material produced by the boron-nitride treatment could be transformed into high speed saws, cutting devices and drill bits that are used for geological exploration and drilling for oil.

13.Separation rings for continuous cast steel in metallurgy. Flow slot for ferrous iron, release agent for continuous cast aluminum(various optical glass release agents)

14.Make any of the Evaporation vessels for capacitor film aluminum plating,picture tube aluminum plating,display aluminum platingand more.

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

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

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

For optical applications, due to the hardness that is high of the c-BN film as well as the excellent transmittance over the entire wavelength range from ultraviolet(from approximately 200 nm)to the far infrared range, it is suitable as a coating on the surface of certain optical components. It is especially suitable for coating of window materials such as zinc selenide(ZnSe)and zinc sulfide(ZnS).In the same way, it has excellent temperature shock resistance and hardness. It is predicted to become an optimal windowing material high power light sources and detectors.
