最近发现了具有优良压电性能的Sr0.9 ^（Na 0.5^ Bi 0.5^）0.1^-Bi 4^ Ti 4^ O 15^（SNBT）化合物。在此基础上，研究了铈对SNBT基陶瓷的改性作用。0.50wt%铈改性SNBT基陶瓷的居里温度和压电常数分别为598 ℃和27 pC/N，其稳定的老化性能和热退火性能表明，铈改性SNBT基材料具有良好的高温应用前景。[出版物摘要]
The composition of Sr^ sub 0.9^(Na^ sub 0.5^ Bi^ sub 0.5^)^ sub 0.1^-Bi^ sub 4^ Ti^ sub 4^ O^ sub 15^(SNBT) with excellent piezoelectric properties had been found recently. And basis on that, the effect of cerium modification SNBT-based ceramics was investigated in this paper. The Curie temperature and piezoelectric constant (d^ sub 33^) for the 0.50 wt% cerium-modified SNBT-based ceramics were found to be 598 C and 27pC/N, respectively, which, together with the stable aging performance and thermal annealing properties, demonstrated that the cerium-modified SNBT-based materials are promising candidates for high-temperature applications.[PUBLICATION ABSTRACT]
