Abstract

Multiferroic BiFeO ₃ and Bi _0.92Dy _0.08FeO ₃ ceramics were prepared to study their crystal structures and piezoelectric properties. BiFeO ₃ exhibits rhombohedral phase below 810 °C. Although Bi _0.92Dy _0.08FeO ₃ ceramic also shows rhombohedral phase at room temperature, it allows the coexistence of rhombohedral phase and orthorhombic phase at 460-650°C. Both samples have maximum polarizations of >21 μC/cm ² and piezoelectric d ₃₃ values of ∼37 pC/N at room temperature. Their polarized slices show the dielectric anomalies and impedance anomalies because of vibrating resonances below 500°C, and the thickness vibration electromechanical coupling factor is ∼0.6 and ∼0.4 for BiFeO ₃ and Bi _0.92Dy _0.08FeO ₃, respectively. The vibrating resonances confirm piezoelectric responses. Furthermore, samples impedance and resistance decrease fast with temperature increasing, which screens piezoelectric response above 550°C. © 2012 Elsevier Ltd. All rights reserved.
