METHOD FOR MANUFACTURING NIOBIUM OXIDE, NOBIUM OXIDE OBTAINED BY THIS MANUFACTURING METHOD, METHOD FOR MANUFACTURING NIOBIUM PHOSPHATE AND NIOBIUM PHOSPHATE OBTAINED BY THIS MANUFACTURING METHOD

摘要

Disclosed are niobium oxide having a high catalytic activity and high performance niobium phosphate. Niobium oxide is prepared by reacting a niobium compound, a chelating agent and a catalyst in a solvent in an inert gas atmosphere. Niobium oxide thus prepared is added phosphoric acid for phosphorylation in order to prepare niobium phosphate.
