<P>PROBLEM TO BE SOLVED: To provide a method for producing barium titanyl oxalate, whereby barium titanate having excellent crystallinity irrespective of small particle diameter can be obtained by an oxalate technique, and to provide a method whereby fine barium titanate having excellent crystallinity can be produced. <P>SOLUTION: In this method for producing barium titanyl oxalate, 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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
