Research on the Performance of SiAlON-Graphite-SiC Composites
Based on SiC grains and powder, flake graphite, AlN powder, Silicon powder, sintered alumina ultra-fine powder as the starting materials, the sample of SiAlON-Graphite-SiC composites was prepared by firing under N2 atmosphere at 1 550°C and then analyzed in terms of high temperature performances by XRD, SEM and EDAX etc. The interrelation between composition, structure and performance of the material was also investigated. It indicates that this material provides excellent thermal shock resistance and molten alkali resistance, also proper oxidation resistance and applicable as the inner lining of the blast furnace.
