| 摘要 |
The present invention provides a production method for an aqueous dispersion of titanium oxide particles, the production method comprising: a first step (a) in which an aqueous slurry of titanium oxide particles is subjected to wet dispersion in a stirred media mill or a high-pressure dispersion device and in the presence of 15-250 mol parts of acetic acid and 15-90 mol parts of nitric acid with respect to 100 mol parts of titanium oxide, and a pre-washing aqueous dispersion of titanium oxide particles is obtained; and a second step (b) in which the pre-washing aqueous dispersion of titanium oxide particles obtained in the first step (a) is washed. The present invention further provides a production method for a liquid dispersion of titanium oxide particles in alcohol, the production method comprising a third step (c) in which the carrier fluid of the aqueous dispersion of titanium oxide particles obtained in the second step (b) is replaced with an alcohol solvent. |
