PROBLEM TO BE SOLVED: To provide a method for separating and recovering particles of an inorganic oxide from a reaction liquid without aggregating, and preserving the particles in such a shape that the inorganic oxide can be returned to the monodisperse state at any time, and a method in which even when an inorganic oxide is fired at a high temperature of several hundred°C or above, the particles do not sinter mutually. SOLUTION: A method for producing an inorganic oxide comprises adding a nonionic polymeric flocculant to a suspension of particles of an inorganic oxide and recovering the particles of the inorganic oxide, wherein solid CO<SB>2</SB>is preferably added to the suspension after adding the nonionic polymeric flocculant.
