英文摘要：

Using neodymium chloride （NdCl3·6H2O） and sodium soda （Na2SO4） as raw materials, this paper studies the preparation of neodymium color powder by molten salt method. In the course of preparing photochromic pearlescent pigment, the influence factors, including composition and dosage of molten salt, sintering temperature and time are investigated. The characters of synthesized powders are determined by SEM, XRD, and EDAX. The optimal process parameters of synthesizing photochromic pearlescent pigment are studied. The results show that this pigment is characteristics of acid resistance, alkali proof and good photochromism.
