The present invention relates to a method of manufacturing the inorganic oxide particles go through the step of drying the particles obtained at least, and then coagulating the dispersion obtained by performing the hydrolysis and polycondensation of a metal alkoxide in the presence of a basic catalyst, and filtered, a step of coagulating the dispersion, during the dispersion of carbon dioxide, characterized in that is carried out in the I coagulation, including at least one compound of selected from the group consisting of ammonium carbonate, ammonium hydrogen carbonate, and carboxylic acid ammonium was added state, It relates to a process for the preparation of the inorganic oxide particles. In addition, inorganic oxide particles obtained by the method of the present invention has a high purity, and is excellent in fluidity.
