The "dispersing and grinding"combined process was studied for dispersing TiO2.The dispersity of TiO2 particles was characterized as viscosity and particle size.The particle size and morphology of TiO2 before and after dispersing were observed using TEM.Effects of the dispersing agents and their addition amount,the size of grinding medium and grinding time on the dispersion of TiO2 were discussed.The results show that the optimum process conditions for dispersing TiO2 are as follows:sodium metasilicate as the dispersing agent with addition amount of 0.2%(mass ratio) for TiO2,ZrO2 as grinding medium with size of 0.4 μm and 25 min of the grinding time.The average particle size of TiO2 obtained under the optimum conditions is 265 nm with uniform particle size distribution and steady dispersing effect.
