Sericite-TiO2 composite particle material was prepared via mechano-chemical method. SEMEDS and XPS ananlysis indicates that the surface of the sericite were coated by the TiO2 layers and the Ti4+ cations were anchored by formation of SiOTi bonds. Otherwise, the TiO2-coated sericite powders have higher light scattering indexes and other more outstanding properties than the naked sericite powders. Especially, the whiteness, adsorbed value, and hiding power indexes of the rutile TiO2-coated sericite powders were higher than those of the anatase TiO2-coated sericite powders. Hence, rutile TiO2-coated sericite powders can be substitute for the titanium dioxide pigment.
