PURPOSE: A method for manufacturing complex metal oxide powder is provided to uniform the particle of the complex metal oxide powder in a perovskite structure based on a low temperature process. CONSTITUTION: Two or more kinds of metal organic compounds or metal salts are respectively dissolved in a solvent and are mixed. A precipitating agent is added into a mixed solution to form complex metal precipitates. A gelating reaction is implemented to form complex metal compounds. The compounds are thermally treated at a temperature between 800 and 1100 degrees Celsius. The metal organic compounds or metal salts include metal selected from Ba, Mg, Ca, Pb, Ti, Fe, Sr, Zr, Ta, Bi, Ta, and Nb. The precipitating agent is selected from K_2CO_3, KOH, and the mixed solution of the same. |
