Abstract

(1-x)Bi_0.5(Na_0.82K_0.18)_0.5Ti_0.96(Al_0.5Nb_0.5)_0.04O₃-xBi_0.46Na_0.46Ba_0.5La_0.02Ti_0.97Zr_0.03O₃ lead-free ceramics (abbreviated as BNKTAN-100xBNBLTZ) was prepared by the conventional solid reaction. XRD patterns and EDS spectrums revealed that a stable solid solution had been formed between BNBLTZ and BNKTAN. With the introduction of BNBLTZ anti-ferroelectric content, BNKTAN relaxor ferroelectrics exhibited the excellent field-induced-strain for x = 0.04 corresponding to electric field-induced strain S ∼ 0.505 % and normal strain d₃₃* ∼777 pm/V at 65 kV/cm. The large strain response was attributed to the emergence of PNRs in the relaxation process. Additionally, an excellent fatigue resistance performance was obtained within 10⁵ cycles (S = 0.505 %–0.495 % and d₃₃* = 777–758 pm/V, 65 kV/cm). It suggested that prepared ceramics had the great potential to strain sensor and actuators.
