制备黄色云母铈珠光颜料的工艺研究

Study on Preparation of Yellow CeO₂-mica Pearl luster Pigments

摘要: 采用水解法制备氧化铈—云母珠光颜料，利用XRD和SEM对产品进行物相分析及表面结构分析，确定最佳工艺条件为：使用CeCl₄溶液，温度在70~80℃，包覆率在30%~40%，pH值控制在6.50~7.50之间，颜料前驱体升温速率为3~5℃/min，在800℃烧成。

Abstract: A liquid method is developed to synthesize CeO₂-mica pearlescent pigment. Based on test and analysis, the main factors are investigated in detail. XRD and SEM are used to analyze the crystal phase and the surface microstructure of the pigments. The optimum conditions are obtained, temperature 70~80℃, cover rate 30%~ 40%, pH 6.50~7.50, warm-up temperature velocity 3~5℃/min and heat preservation at 800℃.
