METHOD FOR PRODUCING DISPERSION OF MICROPARTICLES OF INORGANIC OXIDE IN ORGANIC SOLVENT

摘要

Provided is a method for producing a highly transparent organic solvent dispersion of inorganic oxide microparticles, characterized by comprising mixing an alcohol dispersion of microparticles of an inorganic oxide, that is selected from zirconia and titania, with a silane coupling agent in the presence of an acid in a temperature range of -20 to 60°C, surface-treating the inorganic oxide microparticles by stirring, and then replacing the alcohol by a lipophilic organic solvent.
