The laboratorial study on the technology of forming TiO2 film on the surface of kaolin particle by liquid deposition process was carried out. The laboratorial results have shown that the key factors influencing the TiO2 film forming effect are the temperature and time surface modification reaction, the density of matrix suspension, the stirring velocity and the calcinations temperature. The measurement of the covering property on the final product was carried out. The measured results have shown that the covering property of kaolin can be greatly improved as kaolin particle is coated with certain thickness of titanium dioxide film, therefore, the film kaolin could be used as the succedaneum of titanium white.
