摘　　要：设计并研究了一种新型五元系压电陶瓷材料Pb(Mg1/3Nb2/3)a(Mn1/3Nb2/3)b(Mn1/3Sb2/3)cZrdTieO3(PMMSN).以材料的准同型相界附近的组成为研究对象,采用普通合成法、不同合成路径的先驱体法进行材料合成,通过添加低温烧结促进剂实现低温烧结,并研究其对材料性能的影响.结果表明,三组元复合先驱体法合成材料的性能最佳,1100℃烧结样品的性能参数为Qm=1916,kp=0.56,d33=326pC/N,ε33T/ε0=1349,tanδ=0.0043.添加Si O2,CdO可使材料烧结温度降低到850℃～950℃,且基本保持了材料的特性,在低温共烧叠层功率型压电陶瓷器件方面显示出好的应用前景.A new quinary system Pb(Mg_ 1/3 Nb_ 2/3 )_ a (Mn_ 1/3 Nb_ 2/3 )_ b (Mn_ 1/3 Sb_ 2/3 )_ c Zr_ d Ti_ e O_ 3 piezoelectric ceramics material was designed and studied.For this PMMSN material composition which located near the morphotropic phase boundary,material was prepared by conventional method and different precursor method.The sintering temperature could reduced by adding a amount of low-melting additives. Its affection on the properties of the material was studied.Result shows,the material performs the be...
