Abstract

This paper focuses on synthesis technology for an MgO-SiC-C powder using light burnt magnesia, silicon and carbon as main raw materials. Effects of technological parameters such as sintering temperature and additives were investigated in order to fabricate an MgO-SiC-C powder with good oxidation resistance and erosion resistance. The results show that additives do influence the structure of the composite powder, with clusters of SiC crystals synthesized in situ and located on the surface of graphite. The appropriate amount of CuS used for composite fabrication was 0.8 to 1%.
