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 metal oxide particles according to the present invention comprises: a step of providing an aqueous dispersion which comprises 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 and a hydrophobic complexing agent and a hydrophilic complexing agent both coordinated with the transition metal ion; a drying step of drying the aqueous dispersion to produce a dried material; and a burning step of burning the dried material.
