Abstract

0.15BiScO3-0.85(Pb1-3x/2Bix)(Ti0.98Mn0.02)O3 (x=0.04~0.10), were prepared by using conventional solid phase processing. The results of X-ray diffraction (XRD) show that the ceramics have a single phase tetragonal perovskite structure. The ceramics, poled by normal poling process, have piezoelectric coefficient d33, planar electromechanical coupling factor kp and thickness electromechanical coupling factor kt of 50~60pC/N, ~11% and ~30%, respectively. A greatly high mechanical quality factor Qm of 1540 was obtained at x=0.08. The Curie temperature (Tc) is in the range of 520??????550 ??_C, higher than 490 ??_C of pure PbTiO3. The combination of good piezoelectric properties and high Tc make these ceramics suitable for elevated temperatures piezoelectric devices.
