发展了一种可在冷却阶段析出锐钛矿的结晶釉的制备方法，采用TG-DSC、XRD等方法分析了该结晶釉的析晶过程，并研究了釉的析晶动力学。结果表明：熔块先在升温阶段析晶，高温时熔化，冷却保温阶段再次析晶；结晶釉中析出的晶体种类和数量主要与釉的冷却保温制度有关，700℃下保温有利于获得锐钛矿相含量较多的结晶釉；利用Kissinger公式计算的锐钛矿的析晶活化能为131.8kJ/mol，Avrami指数为1.74；锐钛矿的析晶是体积析晶，晶体呈三维生长；结晶釉表面的显微硬度为6.33GPa，与传统陶瓷釉面相当，具有较好的表面硬度和易洁性。此外，化学组成对釉的性质有较大的影响，TiO2含量的增加提高了釉中锐钛矿的析晶量；Al2O3含量的变化可调整釉的烧成温度，以适应不同种类陶瓷的烧成制度。

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.
