Abstract: The vitreous tiles in this study are made from the materials using in the industrialization, including kaolin clay, feldspar,quartz after we confirmed the best component. The tiles are sintered and refrigerated at different rates. The XRD results show that the major crystal constitutes are mullite and quartz，and the result is the best at 25℃/min rate; The SEM tests show that the tile has the highest intensity, the least amounts of air holes and cracks at 25℃/min rate, because fibriform crystalloids formed in the tile. The ability of pollute -resistion is boosted up, the intensity is added by 11%~17%, and the wetting-angle on the tile's surface is reduced by 5%~20% after polishing.
