Preparation of Ba(Mg1/3Ta2/3)O3 Using Oxine

Abstract
A solution containing Mg2+ and Ta5+ 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 BaCO3 powder and fired again at high temperatures to obtain Ba(Mg1/3Ta2/3)O3 (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.
