【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.更多还原

【Abstract】 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（t_g,t_p）,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.更多还原
