摘　　要：研究了双包覆层Cr2O3／TiO2／MiCa彩色珠光颜料的制备方法；探讨了膜层晶体生长模式，[Cr（H2O）6]3＋水解过程与影响水解的因素；Cr2O3膜层包覆率、煅烧温度与颜料色调及光学性能的关系。In this paper, a new method is proposed on the preparation of colored pearl pigments of covering-layer Cr2O3/TiO2/MiCa. The forming pattern of membrane layer, the hydrolysis process of [Cr (H2O)6]3+ and some factors affecting the hydroysis are studied. In addition, the relations among the coating rate of Cr2O3, calcination temperature with hue and optical properties are researched.
