摘要：

Barium titanate (BaTiO3, BT)-bismuth titanate magnesium oxide (Bi(Mg1/2Ti1/2)O-3, BMT)-bismuth ferrite (BiFeO3, BF) solid solution ceramics were prepared using a conventional solid-state synthesis, and their piezoelectric properties and microstructure were investigated. X-ray diffraction (XRD) patterns revealed the single phase of perovskite oxide for 0.3BT-0.1BMT-0.6BF ceramics. Strain electric field curves of the sample with 0.3BT-0.1BMT-0.6BF exhibit ferroelectric butterfly-like curves. A strain maximum/electric field maximum (S-max/E-max) was 330 pm/V. Transmission electron microscopy revealed dot-like domains(Nanodomains) inside the ferroelectric domain structures in the 0.3BT-0.1BMT-0.6BF. (C) 2012 Elsevier Ltd and Techna Group S.r.l.
