摘要
研究了无铅型铁电陶瓷x(Bi0.5 Na0.5) TiO3-y(Bi0.5 K0.5) TiO3-zBaTiO3 (x = 0.79, y = 0.14, z = 0.07,简称BNBK79)的压电、铁电和力学响应的非线性特性。利用线性可变差动变压器(LVDT)测量系统实现了微小的机械变形和极化测量。超声波在外部直流电场作用下的传播速度也被确定。在足够强的电场作用下,可以改变自发极化的取向。这导致了极化电场(D-E)、应变电场(S-E)和超声波速度电场(v-E)关系的非线性行为。在矫顽力场上方观察到响应呈蝴蝶状。所描述的BNBK79陶瓷是无铅执行器应用的重要候选者。
Hysteresis measurements of lead-free ferroelectric ceramics BNBK79 (Bi0.5Na0.5) TiO3-(Bi0.5K0.5) TiO3-BaTiO3
The research deals with nonlinear properties of piezoelectric, ferroelectric and mechanical response of the lead-free type ferroelectric ceramics x(Bi0.5 Na0.5) TiO3-y(Bi0.5 K0.5) TiO3-zBaTiO3, where x = 0.79, y = 0.14, and z = 0.07, in short form BNBK79. Small mechanical deformation and polarization measurements are realized using LVDT (Linear Variable Differential Transformer) measuring system. Velocities of ultrasound wave propagation in presence of an external DC electric field are also determined. The orientation of spontaneous polarization can be switched under the action of sufficiently strong electric fields. This causes the nonlinear behaviour of polarization-electric field (D-E), strain-electric field (S-E) and the velocity of ultrasonic waves-electric field (v-E) relationship. Butterfly shape of the responses is observed above the coercive field. The described BNBK79 ceramics is significant candidate for lead-free actuator applications.
