In order to find the causes which affect the cleanliness of TiO2 by sulfate process,the estima-tion method for cleanliness during the dispersity testing was studied.The result shows that the cleanliness is a key factor influencing the dispersity evaluation,while the coarse particles in the product are the main influencing factors to the cleanliness of TiO2.According to the comparative analysis,the impurity parti-cles in the domestic TiO2 mainly consist of Ca,Al and Si with the maximum particle size of 210 μm,while the main component of coarse particles in foreign titanium dioxide is TiO2 with the size less than 30μm.The cleanliness and dispersity of TiO2 can be improved by screening the coarse particles from the slurry after inorganic surface treatment.
