摘　　要：以石英、硼砂等为主要原料,添加适量的氧化铁,采用普通的陶瓷釉制备工艺,制备了低温无铅砂金釉,研究了烧成条件及釉层厚度与砂金釉结晶性能的关系,采用SEM等现代测试手段表征了釉层的厚度及结构。结果表明:当釉层厚度约为400μm,1040℃保温75min时,可获得漂亮的棕底砂金釉,釉层中的晶体呈短柱状。In this paper,low-temperature lead-free gold dust glaze was prepared by conventional process,using quartz and borax as the main raw materials,and iron oxide as a dopant.The influence of firing conditions and the thickness of glaze on crystalline performance were studied.The microstructure and thickness of glaze layer were characterized by means of SEM.The results showed that：when the glaze thickness was about 400μm,the holding time and temperature was respectively 75 min.and 1040℃,a pretty brown glaze with gold dust was obtained in which the crystals were short columns.
