• Mica-based pearlescent pigments are widely applied in plastics, cosmetics, automobiles coatings and other fields, but very few applications in high temperature field are found as their poor heat resistance. In this paper, phlogopite is chosen as a new substrate which is coated by Fe2O3 (doping with La3+) in order to improve the high temperature resistance and luster of the new developed pearlescent pigments. According to the X-ray diffraction (XRD) and scanning electron microscopy (SEM) results, it is found that Fe2O3 nanospheres were coated on the surface of phlogopite homogenously. Colorimeter data imply that doping La3+ can improve the color saturation and purity of pigments apparently. And the optimum amount is 3% lanthanum nitrate addition in this work.
