Abstract

Lead-free piezoelectric ceramics, (Na_0.5Bi_0.5) _0.92Ba_0.08TiO₃ (BNT-BT) have been synthesized by a conventional solid state sintering method. The dependence of temperature on dielectric and ferroelectric properties of lead-free piezoelectric ceramics were investigated. The ceramics exhibit a giant strain with the increase of temperature. The piezoelectric coefficient (d₃₃) is about 149pC/N at RT. The electromechanical properties were explained based on a field induced antiferroelectric-ferroelectric phase transition.
