Abstract Some brown CaTiO3 pigments have been synthesized by calcining the depositions of CaCO3 and Cr dopant on the surface of TiO2 particles. The pigments have a pure phase composition of perovskite and a narrow size distribution ranging from 0.5 to 1.5 μm. These pigments have a low lightness and exhibit dark brown color due to the presence of Cr6+.The doped CaTiO3 pigment with 1% Cr has high NIR reflectance of 79.7% and high solar reflectance of 58%, and the doped pigment coating can lower 8.9 °C for the inner surface of ceramic tiles.
