METHOD OF PRODUCING BARIUM TITANATE

摘要

A method of producing barium titanate that includes making a slurry by dispersing barium titanate powder in a solvent such as ethanol. Then, in a high-pressure vessel, substituting supercritical fluid including carbon dioxide gas, for example, for the solvent in the slurry. Then, separating the barium titanate powder from the supercritical fluid by gasifying the supercritical fluid. Then, performing a heat treatment on the separated barium titanate powders to produce the barium titanate.
