(54) | METHOD FOR PRODUCING PEROVSKITE COMPLEX OXIDE |
(57) A method for producing a highly crystalline perovskite-type complex compound is provided
that exhibits stably a high Seebeck coefficient and a low electric resistivity even
at higher temperatures. A method for producing a complex perovskite-type compound
with less environmental load is also provided. The method comprises a step of dissolving
a nitrate salt containing a rare earth element, a nitrate salt containing an alkaline
earth metal element, a nitrate salt containing manganese, and an organic polymer into
a solvent to form a solution, a step of mixing and stirring the solution, a step of
preparing a precursor powder from the solution through heating and drying thereof,
and a step of calcining the precursor powder in atmosphere.
