dc.description.abstract | A thermotropic phase boundary between non-ergodic and ergodic relaxor phases is tuned in lead-free Bi1/2Na1/2TiO3-based ceramics through a structural transition driven by compositional modification (usually named as "morphotropic approach"). The substitution of Bi(Ni1/2Ti1/2)O-3 for Bi-1/2(Na0.78K0.22)(1/2)TiO3 induces a transition from tetragonal to "metrically" cubic phase and thereby, the ergodic relaxor ferroelectric phase becomes predominant at room temperature. A shift of the transition temperature (denoted as TF-R) in the non-ergodic-to-ergodic phase transition is corroborated via temperature-dependent dielectric permittivity and loss measurements. By monitoring the chemical composition dependence of polarization-electric field and strain-electric field hysteresis loops, it is possible to track the critical concentration of Bi(Ni1/2Ti1/2)O-3 where the (1 - x)Bi-0.5(Na0.78K0.22)(0.5)TiO3-xBi(Ni0.5Ti0.5)O-3 ceramic undergoes the phase transition around room temperature. At the Bi(Ni0.5Ti0.5)O-3 content of x = 0.050, the highest room-temperature electrostrictive coefficient of 0.030 m(4)/C-2 is achieved with no hysteretic characteristic, which can foster the realization of actual electrostrictive devices with high operational efficiency at room temperature. | - |
