摘　　要：由于全世界对环境保护和可持续发展的关注,陶瓷釉料的无铅化研究成为陶瓷科学与技术领域的一个重要议题。利用景德镇地区的传统陶瓷原料,采用Cu^(2+)着色,成功实现吉州窑绿釉无铅化制备,研究了铜釉色彩对烧结温度的敏感特性。结果表明:随着烧结温度升高,釉层黏度逐渐降低,釉面依次呈现青蓝、淡绿、绿色,在1280℃时达到釉面最佳效果。釉面主要以Cu^(2+)的绿色呈色为主,随着烧结温度的提高,Cu^(+)/Cu^(2+)的摩尔比逐渐增大,釉面则从蓝绿色向青绿色转变。样品均存在圆形和蠕虫状2种相分离结构,当烧结温度较高时,相分离结构收缩并进一步生长成大尺寸圆形相分离液滴,发生Mie散射产生白色乳光,加深釉面呈色。吉州窑无铅绿釉的呈色机制是由铜离子价态和相分离结构的协同耦合作用的结果。Introduction Environmental protection and sustainable development have attracted recent attention.Especially,the lead-free reproduction of ancient ceramic glazes with rich historical and cultural values becomes a common concern for both academia and industry.Jizhou kiln is one of the well-preserved ancient kiln sites in China,and is one of the famous folk firing kilns during the Song and Yuan dynasties.Jizhou kiln green glaze is colored in addition to the chemical composition as well as coloring mechanism.The sintering temperature is also one of the key factors influencing the ceramic glaze color,microstructure,and physical properties.However,the current research on the sintering process of copper-green glaze is still insufficient.The lead-free preparation of green glaze from the Jizhou kiln was achieved using the conventional ceramic raw materials in the Jingdezhen area and Cu^(2+)coloring.The influence of sintering temperature on the formation of glaze color,microstructure,and color-presenting mechanism of lead-free green glazed ceramics,as well as the mechanism of the effect of sintering temperature on the glaze's physical properties were systematically investigated.This study provides a scientific guidance and a technical support for the lead-free reproduction of green-glazed porcelain of Jizhou kiln to further promote the protection and inheritance of traditional ceramic culture,and to provide an important reference basis for the sintering behavior of other types of glazes.Methods A base glaze was prepared using 23%(in mass fraction,hereinafter the same)wollastonite,9%talc,20%feldspar,26%quartz,10%kaolin,8%smelter's ash,and 4%zinc oxide(ZnO)from mineral raw materials originating in the Jingdezhen area of Jiangxi Province,China,with 4%CuO as a coloring agent.ZnO(99%analytically pure),CuO(99%analytically pure),and glazes were applied to blanks by an impregnation method(blanks were already 900℃plain firing),and the impregnation time was 20 s.Subsequently,the samples were put into a box-type resistance furnace
