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1 130℃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4 MV/m可以得到较好的压电性能.
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.
