摘要
对PZN-PSN-PMS-PZT五元系压电陶瓷的烧结温度(1200～1280°C)、Zr/Ti与性能的关系以及部分Sr2+、Ba2+取代Pb2+对材料性能的影响进行了研究。实验结果表明:当Zr/Ti=0.455/0.435,掺Sr2+、Ba2+(摩尔分数均为2%)时,在1260°C,2h条件下烧结,样品的品质因数Qm为1671;介电常数εTr3为1294;压电常数d33为285pC·N-1;介质损耗tanδ为0.004;机电耦合系数kp为0.522;居里温度TC为295°C;矫顽场强Ec为19kV·cm-1,显示出该五元系具有很大的应用价值和发展潜力。
In this paper, PZN-PSN-PMS-PZT system piezoelectric ceramics with various Zr/Ti were prepared by traditional method. The range of the sintering temperature was from 1 200 to 1 280 °C. The Q_m,ε~T_(r3),d_(33),tan δ and k_p of the samples are described as a function of the sintering temperature.The optimized results of Q_m=1 671,ε~Τ_(r3)=1 294, d_(33)=285 pC·N^(-1), tan δ=0.4%,k_p=0.522,curie temperature T_C=295 °C and coercive electric field E_c=19 kV·cm^(-1) are obtained at the composition containing 2% Sr^(2+)and 2% Ba^(2+) sintered at 1 260 °C.It indicates that this PZN-PSN-PMS-PZT system has great applied value.
