摘要

(1-x)Bi0.5(Na0.82K0.18)0.5Ti0.96(Al0.5Nb0.5)0.04O3-xBi0.46Na0.466Ba0.5La0.02Ti0.97Zr0.03O3 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.
