采用传统固相法制备了(1-x)Bi4Ti3 O12-xSrBi2 Nb2 O9(BIT-SBN,x=0,0.025,0.050,0.100,0.150,0.200)铋层状无铅压电陶瓷.系统研究了SrBi2 Nb2 O9掺杂对Bi4Ti3 O12基陶瓷物相结构、微观结构以及jie电性能的影响.结果表明:所有陶瓷样品均为单一的铋层状结构;当SBN掺量为0.100时,样品具有最佳的电性能:d33=21 pC/N,相对密度ρ =98.1％,机电耦合系数kp=8.26％,εr=220,介电损耗tanδ =0.29％,剩余极化强度Pr=9.128 μC/cm2,Tc=594℃.同时,SBN的引入增强了样品的抗老化性和热稳定性.
