1. 80-100nm, 800nm, 1-10um
2. 99.8%, 98%+, 99.5%
3. Hexagonal, spherical
4. Good conductors of heat
5. Electrical insulation
Application:
1. Condition of high temperature special electrolysis, resistance material.
2. Solid lubricant. Used as high temperature lubricant and release agent.
3. Transistor heat-seal desiccating agent, plastic resin and other polymer additive.
4. Used as high temperature, high pressure, insulation and heat dissipation component. Mould pressing BN can be made high-temperature crucible and other products. Can be used as superhard material. Be suitable for geological prospecting, the oil drilling bit and high-speed cutting tools.
5. Aerospace industry heat shield material. Used in high pressure and frequency electric, plasma arc insulators, automatic welding thermostability stents coating, high-frequency induction furnace material, semiconductor solid admixtures, atomic reactor structure materials, prevent neutron radiation packing materials, radar pass-through box, radar antenna medium, composition of rocket engine, etc.
6. In catalytic agent participation, through high temperature and pressure process, can be converted into the hard as diamond cubic BN. Can be used as metal processing abrasive. Its characteristic is processing surface temperature low and parts surface defect less.
7. Use as additive. BN fiber, is made from BN, is in the module high function fiber and inorganic synthesis engineering materials. Can be use in chemical industry, textile industry, astronavigation technology, etc.
