A solution containing Mg 2+ and Ta 5+ was added to an aqueous ammonia solution of oxine, resulting in a precipitate. After the precipitate was thermally decomposed and fired, it was mixed with BaCO 3 powder and fired again at high temperatures to obtain Ba(Mg 1/3 Ta 2/3 )O 3 (BMT). This method resulted in BMT formation at temperatures lower than those used in the conventional mixed‐oxide method, and single‐phase BMT formed directly at 1300°C without intermediates.
