The composition of Sr 0.9 (Na 0.5 Bi 0.5 ) 0.1 -Bi 4 Ti 4 O 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 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.
