ABSTRACT:
The present invention provides a new and improved method of making barium titanate powder. The method includes the steps of providing a solution comprising oxalic acid and titanium oxychloride, maintaining the solution at a predetermined temperature, adding barium carbonate to the solution thereby precipitating barium titanyl oxalate, and calcining the barium titanyl oxalate so as to provide the barium titanate powder.
