| Abstract: | Titania-mica precursor was prepared by method of forced hydrolysis using TiCl4 solution as raw materials and mica as substrate.Using Co(NO3)2·6H2O and Al(NO3)3·9H2O as raw materials,Spinel CoAl2O4 was prepared by chemical coprecipitation method,and the blue titania-mica pearlescent pigment was prepared based on the technology of coating spinel CoAl2O4 on the titania-mica precursor.FT-IR and XRD were used to characterize the samples and the properties of the samples was determined,the conclusion was that rutile TiO2 and spinel CoAl2O4 were coated onto the surface of the blue pearlescent pigment,it had good optical properties like pearl and the properties were stable. |
