摘　　要：采用锂辉石代替部分长石,显著降低了釉的高温粘度,提高了锆乳浊釉的釉面光洁度和耐磨性能。同时用CaO、MgO、ZnO、BaO等完全取代了普通釉料中的K2O,Na2O,在保留了碱金属氧化物的强助熔作用的同时,提高了釉面硬度、增加了釉面耐磨性和化学稳定性。在配方设计中通过优化配比,制备了可在1180℃～1200℃烧成的光泽度良好的耐磨锆乳浊釉。并采用XRD,SEM等现代测试手段对实验釉进行了分析。提出了含Li2O、CaO、MgO、ZnO、BaO锆乳浊的耐磨机理。Spodumene replaces feldspar. Would decrease high temperature viscosity of glaze flux, and improve the glossness of glaze and abrasion resistance. CaO, MgO, ZnO and BaO are used to replace K2O and Na2O in glaze. At the same time, the process do not change Alkali metals Oxide's strong melt helping performance .It would not only enhance surface hardness but also increase abrasion resistance and chemical stability. The Non-alkali zircon opaque glaze could be obtained by designing feasible composition and substituting.The glaze was fired at 1 180 ℃～1 200 ℃. XRD and SEM have been used to study the properties of the glaze. It was pointed out that large amount of zircon microcrystal evenly dispersed in glaze layer resulted in opacification of glaze surface.
