Sr l ± x/ Bi 2 ± y/ Ta 2 O 9 and Sr l ± Bi x 2± y Nb 2 O 9 ceramics were prepared by a solid state reaction method. X-ray diffraction analysis indicated that single-phase of Bi-layered perovskite was obtained. According to Sr/Bi content ratio, Curie temperature( T c ), electromechanical factor( K p ) and mechanical quality factor( Q m ) were measured. The Curie temperature of SBN(SBT) rose from 414 ? C (314 ? C ) to 494 ? C (426 ? C ) when Sr/Bi content ratio was increased. In the case of Sr/Bi content ratio = 0.55/2.3, the maximum value of the mechanical quality factor Q m of SBT and SBN were obtained 3320 and 1010, respectively.y.
