采用常规固相法制备了掺锂、铈改性的Aurivillius型陶瓷Sr0.6（BiNa）0.2Bi2Nb2O9（SBNBN）。X射线衍射（XRD）和拉曼光谱分析表明，锂铈改性SBNBN陶瓷为钙钛矿型正交结构的单相陶瓷。研究了锂和铈取代A位对SBBN基陶瓷结构和电性能的影响。锂和铈的掺杂使SBNBN陶瓷的压电性能显著提高。Sr0.5（BiNa）0.2（LiCe）0.05Bi2Nb2O9陶瓷的居里温度Tc和压电系数d33分别为583 °C和28 pC/N。讨论了SBNBN陶瓷压电性能提高的原因。
Aurivillius-type ceramics, Sr0.6(BiNa)0.2Bi2Nb2O9(SBNBN) with lithium and cerium modification, were synthesized by using conventional solid-state processing. X-ray diffraction analyses (XRD) and Raman spectroscopy revealed that the lithium and cerium modified SBNBN ceramics had a single phase with perovskite-type orthorhombic structure. The effect of lithium and cerium substitution for A site on structure and electric properties of the SBNBN-based ceramics was investigated. Piezoelectric properties of the SBNBN ceramics were significantly improved by the modification of lithium and cerium. Curie temperatureTcand piezoelectric coefficientd33of the Sr0.5(BiNa)0.2(LiCe)0.05Bi2Nb2O9ceramics were 583 °C and 28 pC/N, respectively. Reasons for enhancement in piezoelectric properties of the SBNBN ceramics were discussed.
