METHOD FOR PRODUCING BARIUM TITANATE POWDER, BARIUM TITANATE POWDER, AND BARIUM TITANATE SINTERED COMPACT

摘要

PROBLEM TO BE SOLVED: To provide a fine barium titanate powder in which the growth of grains can be suppressed even if it is fired and a method for producing the same, and to provide a barium titanate sintered compact composed of fine barium titanate crystal grains obtained from such a barium titanate powder.;SOLUTION: The method for producing the fine barium titanate powder comprises the steps of mixing a barium compound which forms barium oxide by thermolysis with a titanium dioxide having a rutile content determined by X-ray diffraction of 30% or more and a specific surface area of 30 m²/g or more and calcining the resulting mixture.;COPYRIGHT: (C)2007,JPO&INPIT
