High Purity BN Ceramic Crucibles For Sintering And Smelting Alloy Ceramics

High Purity Hot-Press Boron Nitride BN Ceramic Crucibles used for sintering and smelting alloy, ceramics, rare earth

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.

Performance

1. High purity, up to 99.7%, no adhesion, no pollution and long service life.
2. The highest operating temperature is 2100℃, with high and low temperature resistance to repeated impact and resistance to carbon corrosion.
3. Used for sintering and smelting alloy, ceramics, rare earth and other maerials.
