摘　　要：合成了钙钛矿结构的 0 .0 8Pb(Fe1/ 3 Sb2 / 3 )O3 -yPbTiO3-(1-0 .0 8-y)PbZrO3 三元系压电陶瓷材料 ,测量并计算了不同y值时的压电常数 (d3 3 )、机电耦合系数 (kp、k3 3 )、机械品质因数 (Qm)以及极化前后的介电常数 (εT3 3 /ε0 ) ,对实验现象进行了简单的讨论 ,得出一些有益的结论 ;实验结果表明当选取合适的 y值时可以获得压电性能良好的压电材料 ,如 y =0 .45时材料的平面机电耦合系数kp、纵向机电耦合系数k3 3 和压电常数d3 3 分别达到 0 .64× 10 -12 C/N、0 .72× 10 -12 C/N和 3 65× 10 -12C/N。Perovskite-structured 0.08Pb(Fe1/3Sb2/3)O3-yPbTiO3-(1-0.08-y) PbZrO3 ternary ceramic has been composed. The piezoelectric and dielectric properties including electromechanical coupling factor, kp, k33, piezoelectric constant, d33, mechanical quality constant Qm and dielectric constant Ε33t/Εo, in room temperature, before and after poled, of different compositions have been measured. These data were shown by figures as a function of the amount of PbTiO3. The results showed that in some composition region this ternary system exhibiting good piezoelectric properties. For example, when y=0.45, the planar electromechanical coupling factor, kp, longitudinal electromechanical coupling factor, k33 and the piezoelectric constant, d33, were found to be 0.64, 0.72 and 365×10-12 C/N, respectively.
