摘　　要：采用传统固相合成法制备了Pb(Mn1/3Sb2/3)O3掺杂的(1–x)(Pb0.92Ba0.02Sr0.06)(Zr0.52Ti0.48)O3-xPb(Mn1/3Sb2/3)O3[xPMS-(1–x)PBSZT]压电陶瓷。通过XRD、SEM和准静态d33仪等手段探讨了PMS掺杂量对xPMS-(1–x)PBSZT陶瓷样品的相结构、显微结构和电性能的影响。结果表明:适量的PMS掺杂有助于降低陶瓷样品的烧结温度,x=0.01的样品在1 230℃烧结具有最大体积密度7.83 g/cm3。当x=0.02时,其具有最佳综合电性能,主要参数为:d33=349pC/N,kp=0.592,εr=1 587,tanδ=0.46%。（1-x）（Pb0.92Ba0.02Sr0.06）（Zr0.52Ti0.48）O3-xPb（Mn1/3sb2/3）O3[xPMS-（1-x）PBSZT] ceramics were synthesized by using a conventional solid state reaction route. By means of SEM, XRD, quasi-static d33 meter, the influences of PMS contents on phase structure, microstructure, piezoelectric and dielectric properties of the ceramics were investigated. The results show that suitable amount of PMS reduces the sintering temperature ofxPMS-（1-x）PBSZT ceramic, when x = 0.0 l, the maximum density （7.83 g/cm^3） of the ceramics sintered at 1 230 ℃can be obtained. When x = 0.02, the ceramics exhibit the optimum dielectric and piezoelectric properties： d33=349pC/N,κp=0.592,εr=1587,tanδ=0.46%.
