| Abstract: | The preparation of wollastonite-TiO2 composite particles through wet mechanical grinding method in the stirred mill was studied. The main effect factors in preparation process were tested and optimized, and the properties and microstructure of the composite particles were characterized. The results indicate that the grinding time of wollastonite substrate, the mechanical force in the process of grinding wollastonite-TiO2 together and pH value have an obvious effect on the properties of wollastonite-TiO2 composite particles. Wollastonite-TiO2 composite particles are formed with the structure of TiO2 coating on wollastonite surface evenly, and the pigment properties of the composite particles are similar to that of titanium dioxide. |
