METHOD FOR PRODUCING BARIUM TITANATE POWDER, BARIUM TITANATE POWDER, DIELECTRIC CERAMIC AND MULTILAYER CERAMIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a method capable of producing fine-grain homogeneous barium titanate powder using a solid phase reaction process.;SOLUTION: In the method for producing barium titanate powder with steps for mixing and calcining barium carbonate powder and titanium oxide powder, acicular powdery barium carbonate particles (particles having a shape which satisfies a major to minor axis size ratio of ≥2) are used as the barium carbonate powder and preferably acicular powdery barium carbonate particles having ≥5.0 m2/g specific surface area are used.;COPYRIGHT: (C)2002,JPO
