Boron nitride is a crystal composed of nitrogen and boron atoms. The crystal structure is divided into: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) and wurtzite nitride Boron (WBN).
Among them, the crystal structure of hexagonal boron nitride has a similar layered structure of graphite, showing loose, lubricating, easy to absorb moisture, light weight and other properties of white powder, so it is also called "white graphite".
Boron Nitride Powder Properties
Boron nitride has chemical resistance properties and is not corroded by inorganic acids and water. Boron nitride is slightly soluble in hot acid and insoluble in cold water, with a relative density of 2.25.
Hexagonal boron nitride is a white crystal with a melting point of nearly 3000°C, high temperature resistance, extremely stable chemical properties, strong acid corrosion resistance, and high electrical insulation properties.
For hexagonal boron nitride, it has these characteristics: low friction coefficient, good high temperature stability, good thermal shock resistance, high strength, high thermal conductivity, low expansion coefficient, high electrical resistivity, corrosion resistance , It can transmit microwave or infrared ray.
Boron Nitride Powder Applications
Boron nitride is mainly used for refractory materials, semiconductor solid-phase doping sources, structural materials for atomic stacks, packaging materials for preventing neutron radiation, rocket engine constituent materials, high-temperature lubricants and mold release agents.
Boron nitride can be used as:
1. Mold release agent for metal forming and lubricant for metal wire drawing.
2. Special electrolytic and resistive 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 anti-oxidation additives, especially for the occasions of resistance to molten metal corrosion, heat-enhancing additives, high-temperature insulation materials.
4. Heat-sealing desiccant for transistors and additives for polymers such as plastic resins.
5. Pressed into various shapes of boron nitride products, which can be used as high temperature, high pressure, insulation and heat dissipation parts.
6. Thermal shielding materials in aerospace.
7. With the participation of catalysts, it can be converted into cubic boron nitride which is as hard as diamond by high temperature and high pressure treatment.
8. The structural materials of the atomic reactor.
9. The nozzles of airplanes and rocket engines.
10. Insulator of high voltage and high frequency electricity and plasma arc.
