摘　　要：采用液相沉积法合成了纳米Fe2O3包覆云母珠光颜料。利用综合热分析仪(DSC-TGA)、场发射扫描电镜(FE-SEM)对样品的热处理工艺和表面形貌进行表征,利用树脂涂卡对珠光颜料的珠光性能进行表征。结果表明,水解包膜温度75℃、pH 3.3、FeCl3溶液浓度为1 mol/L,以10℃/min升至800℃进行30 min煅烧,制得的珠光颜料的表面纳米包覆膜平整致密,具有明亮鲜艳的金黄色珍珠光泽。Nano-Fe2O3 coated mica pearlescent pigment was prepared by liquid deposition. The thermal treatment process and the superficial morphology are characterized by means of DSC-TGA, FESEM and the pearlescent property of products is characterized using resin card. The results show that the compact smooth nano-Fe2O3 film coated pearlescent pigment with shining golden pearl luster was prepared in conditions of hydrolysis temperature for 75 ℃, pH 3.3, c（FeCl3）= 1 mol/L, sintering condition for 10 ℃/min rate to 600 ℃ and maintain 30 rain.
