METHOD FOR MANUFACTURING PEROVSKITE TYPE COMPOUND OXIDE

摘要

PROBLEM TO BE SOLVED: To obtain a mixed dry material with little maldistribution and little aggregation by heating a slurry prepared by wet-blending metal oxides which are raw materials of a perovskite type compound oxide in the presence of a solvent such as water and by bringing pulse combustion gas into contact with the slurry. SOLUTION: A method for manufacturing a perovskite type compound oxide having a composition represented by the formula: ABO3(where A and B each denote a metal element) is provided which includes a step of drying a slurry or solution of inorganic metal compounds by bringing pulse combustion gas into contact with it.
