Abstract
A method of manufacturing a complex metal oxide powder, the method including: preparing a raw material composition for forming a complex metal oxide; mixing an oxidizing solution including an oxidizing substance into the raw material composition to produce complex metal oxide particles to obtain a liquid dispersion of the particles; and separating the particles from the liquid dispersion to obtain a complex metal oxide powder. The complex metal oxide is shown by a general formula ABCO, an element A including at least Pb, an element B including at least one of Zr, Ti, V, W, and Hf, and an element C including at least one of Nb and Ta. The raw material composition includes: at least one of a thermally-decomposable organometallic compound including the element A, the element B, or the element C, a hydrolyzable organometallic compound including the element A, the element B, or the element C, and a partial hydrolyzate and/or a polycondensate of the hydrolyzable organometallic compound; at least one of a polycarboxylic acid and a polycarboxylic acid ester; and an organic solvent.
