Product Description

   The crystal structure of hexagonal boron nitride has a similar graphite layer structure, showing loose, lubricated, easy to absorb, light weight and other properties of white powder. The crystal structure of hexagonal boron nitride has a similar graphite layer structure, showing loose, lubricated, easy to absorb, light weight and other properties of white powder. The product has high moisture resistance and can be used in nitrogen or argon at temperatures up to 2800 ° C. It not only has a low coefficient of thermal expansion, but also has a high thermal conductivity, which is not only a good conductor of heat, but also a typical electrical insulator. The thermal conductivity of BN measured by high purity single crystal at 300k is 730w/mk. The product has high moisture resistance and can be used in nitrogen or argon at temperatures up to 2800 ° C.
