中文摘要：

基于0．36BiScO3-0.64PbTiO3（BSPT64）高温压电陶瓷体系，引入Ga2O3并通过传统固相反应法制备了0．36[BiSc（1-x）CaxO3]-0．64PbTiO3（x=0．001、0．003、0．005、0．008、0．01、0．015、0．02）系列压电陶瓷。X射线衍射分析表明Ga^3＋取代B位的Sc^3＋不影响BSPT64体系的钙钛矿结构。通过对材料介电和压电性能的研究，发现在取代量x=0．01附近，BGSPT64x陶瓷的各项性能表现最优。BGSPT64-0．01陶瓷的压电常数d33、机电耦合系数κp分别为510pC／N和61％，剩余极化强度Pc和矫顽场Ec分别为49μC／cm^2和21kV／cm。研究表明，BGSPT64-0．01陶瓷是一种优良的压电换能器和传感器材料。

英文摘要：

Ceramics of 0. 36 [ BiSc（1 -x） GaxO3]-0.64PbTiO3 （ x = 0. 001 , 0. 003,0. 005,0. 008,0. 01,0. 015, 0. 02） are prepared by conventional solid state reactions when Ga2O3 is doped into 0. 36BiScO3-0. 64PbTiO3 （BSPT64） system. The analysis results of X - ray diffraction reveal that Ga^3 ＋ replacing Sc^3 ＋ does not change the perovskite structure of BSPT64. The dielectric and piezoelectric properties are investigated. The results show that BGSPT64 -0.01 has an optimized characterization, i.e. its piezoelectric coefficient d33 ,planar coupling coefficient κp, remnant polarization Prand coercive field Eoare respectively 510 pC/N,61% ,49 μC/cm^2 and 21kV/cm. The research results show that the BGSPT64-0.01 ceramics is a good candidate material for the piezoelectric actuator and transducers.
