At present, lead zirconate titanate (PZT) based ceramics are most widely applied piezoelectric materials because of their superior electrical properties. However, the evaporation of toxic lead during the fabrication of the ceramics causes an environmental problem. Therefore, there is an increasing interest of investigating lead-free piezoelectric materials to replace PZT based piezoelectric ceramics. Sodium bismuth titanate, (Na0.5Bi0.5)TiO3 (NBT), is a kind of perovskite-type ferroelectric with a relatively large remnant polarization (P= 38 μC/cm2) at room temperature and a relatively high Curie temperature (T= 320 °C) [1]. For its strong ferroelectricity at room temperature, NBT has been considered to be a promising candidate material for lead-free piezoelectric ceramics. However, it is difficult to pole NBT ceramic due to its large coercive field (E= 73 kV/cm), making it unsuccessful in obtaining desired piezoelectric properties. To solve this poling problem, various NBT...
