METHOD FOR PRODUCING BARIUM TITANATE POWDER BY AN OXALATE PROCESS, AND BARIUM TITANATE POWDER PRODUCED BY THE METHOD

摘要

Disclosed is a method for producing barium titanate powder by an oxalate process, and barium titanate powder produced by the method. The disclosed method for producing barium titanate powder comprises a step of synthesizing barium titanyl oxalate, adding amino acid-based compounds and compounds containing carboxylate group to the synthesized barium titanyl oxalate, and wet-milling and spray drying the mixture. In addition, the barium titanate powder produced by the method has a uniform fine particle distribution and a high crystallinity.
