Abstract
Nonstoichiometric SrBi2Ta2O9 (SBT) and SrBi2Nb2O9 (SBN) ceramics were prepared by a solid state reaction method. X-ray diffraction analysis showed that single-phase of Bi-layered perovskite was obtained. With different Sr/Bi content ratios of SBT and SBN, Curie temperature (T C ), electromechanical factor (K p ) and mechanical quality factor (Q m ) were measured. T C of SBN (SBT) rose from 414∘C (314∘C) to 494∘C (426∘C) when Sr/Bi content ratio was increased from 0.55/2.3 to 1.2/1.8. In the most Sr-deficient/Bi-excess ratio of 0.55/2.3, the maximum values of Q m were obtained approximately 1013 and 3325 for SBT and SBN, respectively.
