実験手順

As an example of a starting material suitable for an amorphous complex oxide containing phosphorus and vanadium as the major constituents, a vanadyl phosphate solution was prepared. In 3.0 kg of deionized water, 2.956 kg of 85% phosphoric acid was dissolved, and 2.55 kg of oxalic acid (H2C2O4.2H2O) was further added and dissolved under heating. The solution was heated to 80° C., and 1.842 kg of vanadium pentoxide was gradually added and dissolved while paying a careful attention to the generation of bubbles. Then, the heating was continued for further 10 minutes under the boiling condition to complete the reduction. The solution was cooled, and deionized water was added to adjust the total amount to 10.00 kg, whereby the second component was obtained.
