摘　　要：利用辛基苯基聚氧乙烯醚(tritonX–100)/正己醇/环己烷所形成的水/油型微乳液首先获得了Fe–ZrSiO_4红色陶瓷颜料的前驱体,经煅烧后合成了包裹型的锆铁红陶瓷颜料。通过热重–差热分析、X射线衍射、透射电子显微镜、能谱分析及色度测试等对颜料的形成过程、微观结构及性能进行了表征和分析。结果表明微乳液法所制备锆铁红颜料前驱体为无定形粉末,且残留有一定量的表面活性剂等有机物;该前驱体在600℃以下会发生约45%的质量损失,600℃以上质量几乎不再发生改变。无矿化剂作用下,锆铁红陶瓷颜料的开始形成温度约为1100℃;前驱体在1200℃煅烧并保温1h可获得包裹型锆铁红陶瓷颜料,该颜料红度值较高(a=28.95),且具有较高的包裹率。Precursors of Fe-ZrSiO4 pink ceramic pigment were prepared from a water/oil microemulsion with the system of triton X-100/hexanol/cyclehexane. Iron zircon pink inclusion pigments were obtained after calcination. The preparation process, microstructure and properties of the pigments were characterized by thermogravimetry-differential thermal analysis, X-ray diffraction, transmission electronic microscopy, energy dispersive X-ray spectroscopy and color measurement. The results show that the obtained precursor is amorphous and contains a certain amount of surfactant and other organic materials. About 45% mass loss was observed after heat treatment below 600℃ and no other mass loss was found during heat treatment at over 600℃. The formation of iron zircon pink pigments starts at approximately 1100℃ without the addition of any mineralizer. Iron zircon pink inclusion pigment with high reddish （a＊=28.95） and inclusion percentage can be obtained when calcination is carded out at 1 200℃ for 1 h.
