Method for preparing barium titanate, and barium titanate prepared by same
The present invention relates to a method for preparing barium titanyl oxalate, to a method for preparing barium titanate comprising same, and to barium titanyl oxalate and barium titanate prepared by said methods. The present invention is characterized in that synthesis conditions such as the synthesis temperature and the concentration of a material can be adjusted in the process of synthesizing barium titanyl oxalate, wherein the process is performed by the dropwise addition of an aqueous solution of barium chloride and an aqueous solution of titanyl chloride to an aqueous solution of oxalic acid. According to the present invention, barium titanyl oxalate having a large specific surface area can be prepared after the synthesis, and barium titanate having Ba/Ti mole ratio of 0.999 to 1.001 can be prepared.
