Introduction

Silicon carbide and graphite composite crucible adopts high quality silicon carbide and high purity graphite as main raw materials, which has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, high strength, thermal shock resistance, etc.. Moreover, it has good thermal conductivity, does not pollute the negative electrode material, has good air tightness, and can be used in the negative electrode material cladding and carbonation process, which is conducive to the control of volatile matter of the negative electrode material and the specific surface area.
