Characteristics of Boron Nitride Powder

Boron nitride is resistant to chemical corrosion and is not corroded by inorganic acids and water. The boron-nitrogen bond is broken in hot concentrated alkali. Boron nitride begins to oxidize above 1200°C in the air and decomposes at about 2700°C under vacuum. Boron nitride is slightly soluble in hot acid and insoluble in cold water.

Most of the properties of boron nitride are better than carbon materials. Hexagonal boron nitride: low friction coefficient, good high temperature stability, good thermal shock resistance, high strength, high thermal conductivity, low expansion coefficient, high resistivity, corrosion resistance, microwave or transparent infrared rays.

Boron nitride is a hexagonal crystal system, the most common is graphite lattice, there are also amorphous variants, in addition to the hexagonal crystal form, boron nitride has other crystal forms, including: rhombohedral boron nitride (r-BN), cubic Crystalline boron nitride (c-BN), wurtzite type boron nitride (w-BN).

Overview of Boron Nitride

Boron nitride industrial powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. Boron nitride can withstand temperatures exceeding 2000°C, and depending on the brand, its dielectric strength is close to 1000 volts/mil. Boron nitride is hot-it is pressed as a blank and can be easily processed into bars, bars, plates and even custom shapes.

Application of Boron Nitride

1. Metal forming release agent and metal drawing lubricant.

2. Special electrolytic and resistance materials under high temperature conditions.

3. High-temperature solid lubricants, extrusion anti-wear additives, ceramic composite materials production additives, refractory materials and antioxidant additives, especially additives resistant to molten metal corrosion, heat-resistant additives, high-temperature insulating materials.

4. Heat-sealing desiccant for transistors and additives for polymers such as plastic resins.

5. Compressed into various shapes of boron nitride products, which can be used as high temperature, high pressure, insulation and heat dissipation parts.

6. Aerospace thermal shielding materials.

7. With the participation of catalysts, it can be converted into cubic boron nitride with hardness like diamond after high temperature and high pressure treatment.

8. The structural materials of the atomic reactor.

9. Airplane and rocket engine nozzles.

10. High-voltage and high-frequency electrical insulators and plasma arc insulators.

11. Packaging materials to prevent neutron radiation.

12. The superhard materials made by boron nitride processing can be made into high-speed tools and drill bits for geological exploration and oil drilling.

13. Metallurgical continuous casting steel isolation ring, amorphous iron launder, continuous casting aluminum mold release agent (various optical glass mold release agents)

14. Production of evaporation boats for various capacitor film aluminum plating, picture tube aluminum plating, display aluminum plating, etc.

15. All kinds of fresh-keeping aluminum-plated packaging bags, etc.

16. Various laser anti-counterfeiting aluminum plating, brand hot stamping materials, various cigarette labels, beer labels, packaging boxes, cigarette packaging boxes, etc.

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

In terms of optical applications, due to the high hardness of the c-BN film, it has high transmittance in the entire wavelength range from ultraviolet (about 200nm) to far infrared. It is suitable as a surface coating for some optical components, especially as zinc selenide ( Coating of window materials such as ZnSe) and zinc sulfide (ZnS). In addition, it has good thermal shock resistance and hardness, and is expected to become an ideal window material for high-power lasers and lasers. detector.
