Features:
This product has a crystal structure similar to graphite layered structure, showing loose, smooth, easily absorbed, light and other traits. Theoretical density: 2.29g/cm3, mohs hardness: 2, and extremely stable chemical properties. In the use of nitrogen or argon, temperatures can reach up to 2800 ° c. It not only has a low coefficient of thermal expansion, but also high thermal conductivity. It is a good conductor of heat, and is a typical electrical insulator.
Applications:
As super hard materials, it can be used in subsurface investigation, oil drilling and high speed cutting tools; Metal forming and metal drawing lubricant release agent; A special high-temperature electrolysis state, resistor material; Solid lubricant; Transistors and plastic resin sealing desiccant polymer additives; Pressed into various shapes of boron nitride products, can be used as high temperature, high voltage, insulation, cooling components; The aerospace industry in the heat shielding material; The participation in the catalyst, high temperature high pressure treatment can be converted to hard as diamond cubic boron nitride; Mold release for die casting and injection molding; Thermally conductive filler for polymers; Composite ceramics, e.g. evaporation boats; Starting material for hot-pressed BN parts; Bron nitride has been recognized for its unique properties and versatility. Boron nitride combines such features as electrical insulation, thermal conduction, and high-temperature lubricity. It’s widely used for high voltage high frequency electricity, plasma arc's insulators, automatic welding high-temperature coating, high frequency induction furnace materials, semi-conducting solid phase admixtures, atom reactor's structure materials, preventing neutron radiation's packing materials, radar's pass box, radar antenna's mediums, rocket engine's components, etc. Because of good lubricating property, also it is used as high-temperature lubricants. Mould pressing boron nitride can be used in making high-temperature crucible and other products.
