| 摘 要： | 系统研究(1-y)(Na0.80K0.16Li0.04)0.5Bi0.5]TiO3-yBa(Zr0.055Ti0.945)O3无铅压电陶瓷,获得压电应变常数高达185pC/N的0.94(Na0.80K0.16Li0.04)0.5Bi0.5]-TiO3-0.06Ba(Zr0.055Ti0.945)O3压电陶瓷。样品的晶体结构为三方相、四方相共存,处于准同型相界(morphotropic phase boundary,MPB)附近。该类陶瓷室温MPB的摩尔(下同)含量为0.050y0.065。样品y=0.060在40°左右的(003)、(021)双峰与46.5°左右的(002)、(200)双峰分裂最明显。随着Ba(Zr0.055Ti0.945)O3含量的增加,铁电相-反铁电相相变温度(θd)升高、反铁电相-顺电相相变温度(θm)降低;θd和θm的温差越来越小,材料的弛豫性逐渐降低。

| Abstract: | Lead-free piezoelectric ceramics(1-y)(Na0.80K0.16Li0.04) 0.5Bi0.5TiO3-yBa(Zr0.055Ti0.945) O3 were systematically investigated. The 0.94(Na0.80K0.16Li0.04) 0.5Bi0.5TiO3-0.06Ba(Zr0.055Ti0.945) O3 ceramics with a piezoelectric strain constant as high as 185 pC/N was obtained.The structure of the sample can be seen in the results,with the morphotropic phase boundary(MPB) of the ceramics lying in the composition mole content(the same below) of 0.050
