METHOD FOR PRODUCING BARIUM TITANYL OXALATE AND METHOD FOR PRODUCING BARIUM TITANATE

摘要

The purpose of the present invention is to provide a method for producing barium titanyl oxalate, whereby barium titanate offering excellent crystallinity irrespective of small particle diameter can be obtained by an oxalate technique. A further purpose is to provide a method whereby fine barium titanate offering excellent crystallinity can be produced. The present invention is a method for producing barium titanyl oxalate, the method being characterized in that an aqueous solution (B solution) including titanium tetrachloride is added to and reacted with a solution (A solution) containing at least oxalic acid and barium chloride; and preferably, the A solution is obtained by bringing oxalic acid and barium chloride into contact with each other in a water solvent.
