<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a complex metal oxide powder by which the complex metal oxide powder can be obtained by an extremely simple process. <P>SOLUTION: The method of manufacturing the complex metal oxide powder includes: a process of preparing a raw material composition for forming a complex metal oxide; a process of 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 a process of separating the particles from the liquid dispersion to obtain a complex metal oxide powder. The complex metal oxide is shown by general formula: AB<SB>1-x</SB>C<SB>x</SB>O<SB>3</SB>, 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. <P>COPYRIGHT: (C)2008,JPO&INPIT |
