Preparation of (Bi_1/2K_1/2)TiO3-Bi(Mg_1/2Ti_1/2)O₃-BiFeO₃ Ceramics Withnanodomain Structure and their Piezoelectric Properties

Abstract:

Lead-free (Bi_0.5K_0.5)TiO₃)-Bi (Mg_0.5Ti_0.5)O₃-BiFeO₃ (BT-BMT-BF) ceramics were prepared by a conventional solidstate synthesis. Synchrotron x-ray diffraction studies indicated two compositional phase boundaries. An increased strain of 0.070% was obtained at 50 kV/cm, 1 Hz, 25 °C for one of the phase boundary compositions of 0.45BKT-0.1BMT-0.45BF with the temperature of the dielectric maximum of 331 °C.
