THE PREPARING METHOD OF MULTICOMPONENT PEROVSKITE NANO-POWDER USING HYDROTHERMAL SYNTHESIS

摘要

A method for manufacturing multicomponent perovskite nano-powder using hydrothermal synthesis is provided to single phase multicomponent perovskite nano-powder without the use of hydrocarbon-containing materials or metallic mineralizers(KOH, NaOH, etc.). A method for manufacturing multicomponent perovskite nano-powder using hydrothermal synthesis comprises the following steps of: weighing titanium-containing hydroxide and barium-containing hydroxide such that the ratio of Ba/Ti is 1.01~1.02; mixing the titanium-containing hydroxide and barium-containing hydroxide to prepare slurry; hypothermally treating the slurry with hot water to prepare first barium titanate powder; washing the first barium titanate powder; and sintering the washed first barium titanate powder to obtain perovskite nano-powder. The nano-powder has a tetragonal structure.
