METHOD FOR PRODUCING PEROVSKITE COMPLEX OXIDE AND PRODUCING APPARATUS THEREOF

摘要

PURPOSE: A manufacturing method of perovskite-type complex oxides, and a manufacturing device thereof are provided to reduce contents of a hydroxyl group inside perovskite-type complex oxide particles. CONSTITUTION: A manufacturing method of perovskite-type complex oxides comprises the following steps: heating a raw material solution including titanium dioxide powder inside a sealing container; and reacting hydroxide of elements composed of an A-site component with the heated material solution. In the second step, the temperature of the raw material solution is 100 deg. Celsius or higher. The reaction product of the second step is heat-treated at 800-1,000 deg. Celsius. A manufacturing device(10) of the perovskite-type complex oxides comprises an encapsulation container(12), a heating tool, and a feeding tool.
