| 摘 要： | 采用传统固相烧结法,制备了CaBi4Ti(1-x)NbxO1(5x=0.00-0.05,CBT-N)系铋层状结构无铅压电陶瓷。研究了Nb5+掺杂对CBT压电陶瓷压电与介电性能的影响。研究结果表明:添加Nb5+离子,改善了CBT陶瓷的烧结特性,提高了瓷体的致密度。Nb2O5的引入降低了CBT系列陶瓷的介质损耗,改善了陶瓷的压电与介电性能。当掺入量x=0.04(CaBi4Ti0.96Nb0.04O15)时制备的CBT基铋层状压电陶瓷具有优异的压电性能:d33=14pC/N,Qm=3086,εr=212,tanδ=0.0041,kt/kp=1.681。

| Abstract: | Leadless CaBi4Ti(1-x)NbxO15(x=0.00-0.05,CBT-N) bismuth-layered structural piezoelectric ceramics was prepared by solid state sintering process.Effects of Nb5+ doping on the piezoelectric and dielectric properties of CBT ceramics were studied.Results showed:the doping of Nb5+ improved the sintering properties and density of CBT ceramics;the addition of Nb2O5 lowered the dielectric loss and improved the piezoelectric and dielectric properties.When the doping amount x=0.04,the CaBi4Ti0.96Nb0.04O15 bismuth-laye... |
