Abstract

BiFeO₃-PbZrO₃-PbTiO₃ ternary solid solution system was investigated for the development of piezoelectric ceramics with high Curie temperatures. The search for the morphotropic phase boundary (MPB) compositions in this ternary system started from mixing two MPB compositions: 0.70BiFeO₃-0.30PbTiO₃ and 0.52PbZrO₃-0.48PbTiO₃. The content of PbTiO₃ was then further fine tuned in order to reach the appropriate volume fraction between the rhombohedral and tetragonal phases in the sintered ceramics. It was observed that the sintering temperature has a profound impact on the density, grain morphology, dielectric and ferroelectric properties of the ceramics. The composition that displays the best combined structure and properties was identified to be 0.648BiFeO₃-0.053PbZrO₃-0.299PbTiO₃, with a Curie temperature T_C of 560°C, a remanent polarization P_r of 15.0μC/cm², and a piezoelectric coefficient d₃₃ of 64pC/N.
