Abstract

A method for producing particles containing a metal oxide is provided, and the method includes: feeding a metal oxide sol having a pH of 7 or higher and containing metal oxide colloidal particles as dispersoids and water as a dispersion medium, into a liquid containing a solvent having a solubility in 20° C. water of 0.05 g/100 ml or more and having a relative permittivity of 30 or lower (protic solvent) or of 40 or lower (aprotic solvent) at 20° C., and thereby forming aggregates of the metal oxide colloidal particles in the liquid; and subjecting the aggregates to a treatment such as drying and heating, and thereby converting the aggregates into particles that are insoluble in water. By appropriately selecting the solvent, particles can be obtained in the form of flakes, fibers, spheres, and the like.
