采用传统固相法制备了Pb(Sb1/3 Mn2/3)0.05Zr0.47Ti0.48 O3 (PMS-PZT)压电陶瓷.利用XRD、SEM和EDS等研究PMS-PZT陶瓷体系在烧结过程中形成的过渡液相和形成过渡液相温度(1100℃)附近的升温速率对陶瓷结构、压电和介电性能的影响.结果表明:不同烧结温度下,所有样品均为单一的钙钛矿四方相,过渡液相不会对相的结构有影响,但是当烧结温度较低时,过渡液相在烧结后期以玻璃相在晶界附近富集,对陶瓷的压电和介电性能有很大影响.随着烧结温度和升温速率的升高,PMS-PZT晶粒尺寸增大,晶粒均匀性和规则性得以改善,晶化质量得到提高;d33测试和阻抗分析测试结果表明PMS-PZT样品在1100℃附近以7 ℃·min-1升温速率并在1250℃烧结时具有最好的压电和介电性能:d33 =313 C/N,kp=0.59,Qm=1481,εr=1437,tanδ=0.53％.
