Abstract
In this paper, the common gabbro granite (black) waste in the stone market is used as the main raw material to successfully prepare ceramic crystalline glaze. The best preparation process of crystalline glaze is: the ratio of material, ball and water is 1:2:0.8, the grinding time is 24h, that is, D97=34.68 μm, and the glaze layer thickness is 1.2 mm-1.68 mm, and good quality glaze can be obtained. According to XRD, differential thermal analysis and theoretical calculation of granite, the best sintering system for the glaze with granite as the main raw material is formulated as follows: the sintering temperature is 1220°C-1300°C, the crystallization holding temperature is 1140°C-1160°C, and the holding time is 1h-2h.
