Chemical Composition of Dielectric and Piezoelectric Properties for BaTiO₃-Bi (Mg_1/2Ti_1/2)O₃-BiFeO₃ System Ceramics

Abstract:

1-x-y)BaTiO₃-xBi (Mg_1/2Ti_1/2)O₃-yBiFeO₃ ceramics were prepared by a conventional solidstate synthesis, and crystal structure and electric properties were investigated. Synchrotron X-ray diffraction pattern revealed that a single perovskite phase was obtained for samples at x=0.05-0.15, y=0.46.5-73.5. Splitting of the (111) peak was observed when (x, y) = (0.050, 0.685) and (0.050, 0.735) indicating that crystal structure of samples changed from a pseudo-cubic phase to a rhombohedral phase with increasing BF. As the BF content increased, the Curie temperature increased. The largest maximum strain (S_max) over the applied maximum electric field (E_max) value (S_max / E_max) of 300 pm/V was observed for 0.365BT-0.050BMT-0.585BF at 25 °C and 1Hz with the Curie temperature of 390 °C.
