摘　　要： 不透明珐琅在烧制过程中,其表面会因诸多因素形成某些缺陷,本文采用了显微分析方法对不同工艺烧成珐琅的表面特征进行了分析比较,总结出了一些珐琅烧结后常见的表面缺陷特征,如表面未完全熔融、表面凹坑和橘皮、二次结晶、杂质和固溶体增大等现象,得到处理烧制珐琅表面缺陷的合理方法和建议:釉料上釉时铺料均匀,可避免珐琅出现气泡;釉料颗粒大小均匀,有利于得到更好的珐琅制品;珐琅在烧制过程中恒温处理,可消除部分未熔融表面缺陷;对于结晶型珐琅,建议烧成后直接快速冷却。 Due to some factors,the burnt enamel often has some defects on its surface.In this paper,the microscopic analysis method was used to analyze the surface morphological characteristics of burnt enamel in different process.The authors summarized some common surface defects of enamel after sintering,such as the incompletely melting surface,pits and orange peel surface,secondary crystallization,impurities,and the phenomenon of solid solution growing up.Finally,some reasonable ways were found to deal with the defects of the surface of enamel.(1)If the glaze is evenly spreading,the enamel bubbles can be avoided;(2)The size of the glaze particle should be uniform,which is helpful for the better enamel products;(3)The enamel is treated with constant temperature during the burning process,which can eliminate some of the surface defects;(4)The crystallized enamel is recommended to be cooled directly after burning.
