内容記述 | Piezoelectric properties of SrxBi3-xTa2O9 (x=0.5-1.0) [SBT(x)] ceramics were studied for the purpose of discovering bismuth layered-structure ferroelectrics (BLSFs) with large electromechanical coupling factor kij and mechanical quality factor Qm. Ordinarily fired (OF) samples were prepared by a conventional ceramic technique and the sintering temperature was varied from 1150 to 1250°C. Before the piezoelectric measurement, an enhancement of the ferroelectric properties of the SBT(x) ceramics by Bi substitution was confirmed. The values of the electromechanical coupling factor with radial-extentional mode kp for the SBT(x=0.85) ceramics sintered at 1200°C were found to be the largest (kp=10.9%) in the SBT(x) system. The piezoelectric and related constants of SBT(x=0.8) ceramics were also evaluated. The values of kp (10.6%) and k31 (6.8%) with lentgth-extentional mode were higher than those of other OF-BLSFs ceramics with large coupling coefficients, and k33 (14.0%) with lentgth-extentional mode were comparable. | |||||
