| description | [Object]To provide, for example, titanium oxide fine particles that are less photocatalytically active while maintaining a high refractive index.[Solution]A method for producing a zirconia-coated titanium oxide fine particle dispersion includes (1) a step of preparing a dispersion (1) of titanium oxide fine particles, (2) a step of adding, to the dispersion (1), 1 to 50 parts by mass of an aqueous peroxozirconic acid solution in terms of the mass of ZrO2 per 100 parts by mass of the titanium oxide fine particles, and then aging reaction fine particles (2a) obtained as a result of a reaction between the titanium oxide fine particles and the peroxozirconic acid to thereby obtain a dispersion (2) of a zirconia-coated titanium oxide fine particle precursor (2b), and (3) a step of adjusting the dispersion (2) to have a solid concentration of 0.01 to 10 mass% and then hydrothermally treating the resulting dispersion (2). |
