| 摘 要： | 利用XRD、SEM等技术分析方法,研究了工艺条件对[(Na0.5Bi0.5)0.82(K0.5Bi0.5)0.18]1-xLaxTiO3(x=0~0.1)无铅压电陶瓷的物相组成、显微结构和压电性能的影响。结果表明:提高合成温度至870~900℃有利于主晶相的形成;在1130℃下烧结可得到高致密样品。同时研究了极化工艺条件对材料压电性能的影响:极化温度保持在80~100℃之间,极化电场强度为4MV/m可以得到较好的压电性能。

| Abstract: | The influence of processing factors on phase composition,microstructure and piezoelectric properties of [(Na0.5Bi0.5)0.82(K0.5Bi0.5)0.18]1-xLaxTiO3(x=0~0.1) system lead-free piezoelectric ceramics were investigated by XRD,SEM and other analytic methods. It shows that increasing synthetic temperature to 870 ~ 900℃ is useful to formation of main crystalline phase,and high compact ceramics samples are obtained sintered at 1 130℃. After studied on the effects of polarizing factors on the piezoelectric properties in the system,it shows that polarizing temperature range over 80~100℃ and 4 MV/m polarizing electric field are appropriate for gaining better piezoelectric properties. |
