摘要
以固态氧化物为原料,采用二次合成工艺制备PSN-PZN-PMS-PZT五元系压电陶瓷。研究准同型相界(MPB)附近组成为0.03Pb(Sn1/3dNb2/3)O3-0.03Pb(Zn1/3Nb2/3O3-0.04Pb(MnSb2/3)03-xPbZrO3-(0.9-x)PbTiO3(x=0430-0.460)的陶瓷性能。结果发现:在合成温度860℃、保温3h时可以得到钙钛矿结构。当x=0.435,即Zr/Ti=0.935时,烧结温度1260℃,保温3h,其压电、介电性能在准同型相界处综合性能最佳:ε33T/ε0=1390,d33=300×10-12C/N,Kp=55.1％,Qm=1180。
In the paper, 0.03Pb(Sn1/3Nb2/3)O3-0.03Pb(Zn1/3Nb2/3)O3-0.04Pb(Mn1/3Sb2/3)O3-xPbZrO3-(0.9-x)PbTiO3 (x=0.430-0.460) at near the morphotropic phase boundary (MPB)We're prepared by using two-stage technique with solid oxides as raw materials. The results showed that pure perovskitic structure was obtained at calcination of 860℃. the PSN-PZN-PMS-PZT quinary system exhibited a well-situated property at morphotropic phase boundary. The optimized results of ε33T/ε0 (1390), d33 (300pC/ N), Kp (55.1%) and Qm (1230) were obtained with x=0.435 at sintering of 1260℃ temperatures for 3h.
