METHOD FOR PRODUCING METAL OXIDE PARTICLES

摘要

Disclosed is a method for producing metal oxide particles having high crystallinity and a small primary particle diameter. The method for producing the metal oxide particles according to the present invention comprises: a step of providing an aqueous dispersion comprising a water-soluble transition metal complex and water-dispersible organic polymer particles, wherein the water-soluble transition metal complex comprises one transition metal ion selected from a titanium ion, a tantalum ion, and a niobium ion; as well as a hydrophobic complexing agent and a hydrophilic complexing agent both being coordinated with the transition metal ion; drying the aqueous dispersion to produce a dried body; and firing the dried body.
