Abstract: A method for the preparation of anatase glass-ceramic glaze at the cooling stage was developed in this paper.The crystallization process of this glaze was analyzed by means of TG-DSC and XRD，and the crystallization kinetics was also studied.Experimental results show that the frit precipitates at the beginning of the heating stage，then melts at high temperature，and precipitates again at the cooling and soaking stages.The type and quantity of crystals precipitated in glaze are related to the thermal schedule at the cooling and soaking stages.Soaking at 700℃ is helpful to obtain crystalline glaze with more anatase phase.The crystallization activation energy of anatase calculated by Kissinger equation is 131.8kJ/mol and the Avrami index is 1.74.The crystallization of anatase occurs with a 3-dimension growth mode.The Vickers hardness of the glaze is 6.33GPa，which is comparable to that of traditional ceramic glazes.The glaze also shows good cleanability.In addition，the chemical composition greatly influences the properties of the glaze.The increase of TiO2 content improves the amount of crystallization of anatase，while the addition of Al2O3 adjusts the sintering temperature of the glaze，which makes it adaptable to the firing schedules of different types of ceramic.
