摘要: Abstract Exploring lead-free materials to substitute the commercialized PZT-based compounds is in great demand for development of miniaturized and nonhazardous actuator devices. Here, a new ternary (1-x)(Bi0.5Na0.5)1-yBayTiO3-xBi(Li0.5Ta0.5)O3 (BNBTy-xBLT) solid solution system designed optimize electrostrain performance well-studied BNT ceramics, effects BLT Ba substitutions on phase evolution as well electrical performances ceramics are systematically investigated. All compositions prepared by solid-state sintering process exhibit similar pseudocubic with rhombohedral/tetragonal distortions nanoregions. Through optimizing contents, composition 6.9 mol% 0.8 mol% exhibits maximum unipolar strain ∼0.39% (equivalent normalized d33*∼654 pm/V, 60 kV/cm). Moreover, origin excellent response emphatically analyzed from microscopic (domain structure evolution) macroscopic (TF-R shifting) perspectives, which results electric-field-induced reversible relaxor-ferroelectric transition. These suggest composition-optimized BNT-BT-BLT potential alternate lead-based systems applications.
