Abstract:
1. A method of making an ultrafine metal oxide particle dispersion liquid which comprises (a) providing an ultrafine titanium-based composite metal oxide particle dispersion liquid which is the product of titanium compound hydrolysis in a microemulsion comprising a hydrophobic dispersion medium, water and a surfactant, and in which said titanium-based composite metal oxide is a perovskite oxide represented by MTiO (b) providing a solution containing an organic precursor which forms said titanium-based composite metal oxide which is actually present in the dispersion liquid (a), and (c) combining a quantity of the dispersion liquid (a) with a quantity of the precursor solution (b) such that the resulting ratio of said ultrafine titanium-based composite metal oxide particles in (a) to said composite metal oxide which can be formed by the precursor in the precursor solution (b) is 1:1 to 1:30 in terms of mols/liter of said particles and oxide.
