METHOD FOR PREPARING BARIUM TITANYL OXALATE, METHOD FOR PREPARING BARIUM TITANATE, AND BARIUM TITANATE

摘要

A method for preparing barium titanyl oxalate, a method for preparing barium titanate, and barium titanate are disclosed. The disclosed method for preparing barium titanyl oxalate comprises: a step for preparing a barium compound solution, a titanium compound solution, and an oxalic acid solution (a raw material solution preparation step); a step for making the barium compound solution and the titanium compound solution come into contact with the oxalic acid solution so as to synthesize barium titanyl oxalate [BaTiO(C2O4)2·4H2O] (hereinafter, simply referred to as BTO) (a BTO synthesis step); a step for wet milling the synthesized BTO (a BTO wet milling step); a step for drying the wet milled BTO so as to obtain BTO powder (a BTO drying step); and a step for dry milling the dried BTO (a BTO dry milling step), wherein the BTO dry milling step is carried out until the bulk density of the dry milled BTO is 0.2g/cm3 - 0.50g/cm3.
