Abstract

(Bi1/2Na1/2)TiO3(BNT) piezoelectric ceramics are one of the promising materials that can replace Pb(Zr, Ti)O3(PZT) piezoelectric ceramics due to the high electromechanical strain properties. However, it is still difficult to use practical applications because the required electric field for inducing electromechanical strain is relatively higher than that of PZT ceramics. To overcome this problem, it has been intensively studied on doping impurity or modifying other ABO3 for BNT-based piezoelectric ceramics. Therefore, this study investigated the effects of La2O3 doping on the phase transition behavior and electromechanical strain properties in BNT-SrTiO3 (BNT-ST) lead-free piezoelectric ceramics. In the case of the temperature-dependent dielectric properties, it was confirmed that a phase transition from ferroelectrics to relaxors is induced with increasing La2O3 content. As a result, the electromechanical strain properties of BNT-ST ceramics were improved. The highest Smax/Emax value corresponding to 300 pm/V was obtained at 2 mol% La2O3-dopped BNT-ST ceramics. Accordingly, this study successfully demonstrated that La2O3 doping is effective on the inducing phase transition from ferroelectrics to relaxors and the improving electromechanical strain properties of BNT-ST lead-free piezoelectric ceramics.
