Method for producing granular material containing metal oxide
Abstract:
The method of the present invention for producing a granular material containing a metal oxide includes the steps of feeding a metal oxide sol that contains colloidal particles of a metal oxide as a dispersoid and water as a dispersion medium and that has a pH of 7 or higher, into an aqueous electrolyte solution, so as to aggregate the colloidal particles of the metal oxide, form aggregates containing the metal oxide in the aqueous electrolyte solution, and make the aggregates settle out in the aqueous electrolyte solution; and separating the aggregates from the aqueous electrolyte solution after formation of the aggregates. Thus, a highly productive method for producing a granular material containing a metal oxide can be provided.
