Negligible-hysteresis piezoceramic achieved by multiphase assisting and domain configuration manipulating
High-performance lead-free piezoelectric ceramics with knockdown strain hysteresis are key components in high-precision actuators. However, high strain hysteresis in BaTiO<sub>3</sub>-based ceramics will induce stability degradation, lifespan reduction, and inferior positioning accuracy. Therefore, in this work, (1-<em>x</em>)Ba(Sn<sub>0.11</sub>Ti<sub>0.89</sub>)O<sub>3</sub>-<em>x</em>SrTiO<sub>3</sub>-0.6%wt MnO<sub>2</sub> composition is elaborately designed to reduce strain hysteresis. And ultra-low strain hysteresis (4.8%) is achieved by adjusting phase structure and domain configuration. TEM results reveal that the composition possesses R-O-T-C four-phase, nano-domains, and active polar nano-regions (PNRs) coexistence, meanwhile, PFM results have unveiled that these active PNRs can speedily respond to applied electric field stimulus. These findings provide a feasible path to prepare the piezoelectric compositions with ultra-low strain hysteresis.
