用X射线衍射法研究了Pb[(Zn1/3Nb2/3)(Sn1/3Nb2/3)](ZrTi)O3体系压电陶瓷的结构.探讨了微量元素掺杂对材料晶胞参数的影响,以及电极化前后的状况结果表明:样品均为四方相钙钛矿型结构;掺杂微量元素后晶胞参数略有变化;极化使角区发生90°旋转,微应变增加,表现为晶胞中晶面的峰强反转
The structure of piezoelectric ceramic in Pb[(Zn1/3Nb2/3)(Sn1/3Nb2/3)](Zr,Ti)O3 system was studied by XRD. The effect of added micro element to the lattice constants was also studied.The emphasis was the research of the situation of the samples unpoled an
