In Al-Si-C system, there are many compounds, of which Al4SiC4 is useful as high-temperature structure material and the antioxidant in carbon-containing refractory. In this paper, Al4SiC4 powders were synthesized by using kaolin grog, aluminum and activated carbon as raw materials. The phase changes of the synthesized samples were examined by X-ray diffraction (XRD), and the microstructure was observed by scanning electron microscope (SEM). The effects of synthesis temperature and the proportion of aluminum on phase compositions of Al-Si-C system were investigated. The results show plate-like Al4SiC4 powders can be prepared with optimal ratio of starting materials and synthesis temperature.
