One of the hot spots in the field of materials-boron nitride

As a new type of porous non-oxide material, porous boron nitride has many unique properties such as large specific surface area, adjustable pore size, chemical inertness and good thermal stability. It is used in catalysis, hydrogen storage, gas adsorption and separation.

Porous boron nitride is a new type of non-oxide porous material. The interior is composed of interpenetrating or closed pores. It has a high specific surface area and rich pore structure. The aperture can be adjusted according to the actual application, the chemical properties are stable, and the heat conduction. High magnification, good insulation and hydrophobic properties.

In addition, the porous boron nitride material has special hydrogenation performance and selective adsorption performance, and has great application potential in the fields of hydrogen storage, gas adsorption and separation. According to the definition of the International Union of Pure and Applied Chemistry (IUPAC), porous materials can be divided into three categories according to the pore diameter: micropores (pore diameter less than 2 nanometers), mesopores (pore diameter 2-50 nanometers) and macropores (pore diameter) over 50. nm).

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 a catalyst, 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 for zinc selenide ( Coating of window materials such as ZnSe) and zinc sulfide (ZnS). In addition, it also has good thermal shock resistance and hardness, and is expected to become an ideal window material for high-power lasers and applications. detector.
