Hot-Press Boron Nitride BN Ceramic Horizontal Continuous Casting Separation Rings And Crystal Tubes
Boron nitride belongs to the hexagonal system. Its structure is similar to graphite, and their properties are also similar. Therefore, it is also called " white graphite". It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dessipating material and high temperature insulatiing material. Mohs Hardness 2 can be processed into various shaped parts.
