Abstract

Lead-free 0.96[Bi_1/2(Na_0.84K_0.16) _1/2(Ti(_1-x)Nb_x)O₃]-0.04SrTiO ₃ (BNKTN-ST, with x = 0-0.030) ceramics were synthesized by a conventional solidstate reaction technique. Polarization and strain hysteresis loops indicated a significant disruption of ferroelectric order accompanied by an enhanced field-induced strain (S = 0.438%) with a high normalized strain S_max/E_max of 876pm/Vat 5kV/mm. Their reproducibility was confirmed by the fabrication of a 10-layered stack-type multilayer actuator, which demonstrated a normalized strain S_max/E_max of 720pm/V.
