摘　　要：选择CaO-MgO-Al2O3-SiO2系统作为微晶玻璃釉的基本组成,研究微晶玻璃釉的制备工艺,并考察施釉方法、坯釉结合、添加少量粘土对工艺的影响.结果表明,湿法施釉应考虑制品对釉面平滑度和光泽度的要求,当湿法施釉工艺可以达到釉面细腻光滑时,可以得到具有亚光效果的微晶釉;以烧结坯作为微晶釉的基体时,坯釉结合良好,机械敲击无法使坯釉分离.外加少量高岭土可影响玻璃体起始析晶温度和晶化温度、微晶釉的显微结构和性能,对机械性能如硬度等会造成不利影响,并可能不利于其热力学性能.The basic technology of CaO-MgO-Al2O3-SiO2 system ceramic-glass glaze was discussed. Focal point of the research included glazing method, glaze-body bonding and impact of adding a little kaolin. The result showed： （1） Smoothness and glossiness of glaze should be considered when ware was glazed by wet process glazing. Generally,ceramic-glass glaze by wet process glazing would be mat glaze unless glaze surface was polished. （2） It showed good glaze-body bonding when sintered body was chosen as matrix, and glaze would not be separated from body by mechanical impact. （3） Crystallization temperature （tg, tp）, microstructure and performances of glass were varied by adding a little kaolin to frit. It was bad to mechanical performance of glaze such as hardness and wear resistance, also was thermal performance.
