METHOD FOR PRODUCING BARIUM TITANYL OXALATE AND METHOD FOR PRODUCING BARIUM TITANATE
To provide a method for producing barium titanyl oxalate that gives barium titanate with a small particle diameter and high crystallinity.SOLUTION: A method for producing barium titanyl oxalate, wherein barium titanyl oxalate is produced by mixing and reacting a solution containing oxalic acid (solution A) and a solution containing a titanium source and a barium source (solution B) with each other, the method being characterized by: separately supplying the solution A and the solution B to one end of a reaction liquid channel, mixing the solution A and the solution B with each other within the reaction liquid channel, discharging the reaction liquid out of the other end of the reaction liquid channel, and subsequently performing solid-liquid separation of the reaction liquid; and setting the residence time of the reaction liquid within the reaction liquid channel to 30 seconds or less.SELECTED DRAWING: Figure 1
【解決課題】粒径が小さく且つ高結晶のチタン酸バリウムが得られるシュウ酸バリウムチタニルを製造するための製造方法を提供すること。【解決手段】シュウ酸を含有する溶液（Ａ液）と、チタン源及びバリウム源を含有する（Ｂ液）とを混合して、反応させることにより、シュウ酸バリウムチタニルを製造するシュウ酸バリウムチタニルの製造方法であり、反応液流路の一端側に、該Ａ液と該Ｂ液とを別々に供給し、該反応流路内で、該Ａ液と該Ｂ液を混合し、該反応液流路の他端側から、反応液を排出し、次いで、該反応液の固液分離を行うこと、該反応液流路内での該反応液の滞留時間が３０秒以内であること、を特徴とするシュウ酸バリウムチタニルの製造方法。【選択図】図１
