The present invention provides a method for producing a powdery complex metal oxide by a very simple method.n n n Preparing a raw material composition for forming a composite metal oxide, mixing an oxidizing solution containing an oxidizing material with the raw material composition, generating particles of the composite metal oxide to form a dispersion of the particles, and the dispersion Separating the particles from the powder to form the composite metal oxide in powder form. The composite metal oxide is represented by the formula AB 1-x C x O 3 , the A element includes at least Pb, the B element includes one or more of Zr, Ti, V, W and Hf, the C element is At least one of Nb and Ta, wherein the raw material composition is a thermally decomposable organometallic compound containing the A element, the B element or the C element, the valence containing the A element, the B element or the C element At least one of the decomposable organometallic compound, partial hydrolyzate and / or polycondensate thereof, at least one of polycarboxylic acid and polycarboxylic acid ester, and an organic solvent. |
