Lead-based Pb(Zr, Ti)O3 ceramics have been widely used in high-power piezoelectric applications, but its stable operation at high temperature is still a grand challenge. In this work, the third element Pb(Mn1/3Sb2/3)O3 (PMS) was incorporated into Pb(Zr0.48Ti0.52)O3 (PZT) to design the xPb(Mn1/3Sb2/3)O3-(1-x)Pb(Zr0.48Ti0.52)O3 (PMS-PZT) ternary ceramics through the phase diagram. The ceramics with morphotropic phase boundary (MPB) structure and uniform grain size were fabricated successfully. The dielectric, ferroelectric and piezoelectric properties of the ceramics were probed respectively. Excellent piezoelectric properties (Qm=1595, kp=0.61, d33=318pC/N, tanδ=0.60 %, Tc=300℃) were obtained in 0.075PMS-0.925PZT ceramic, which can be attributed to its MPB structure and the pinning effect of defect dipoles on domain rotation. Moreover, the T-phase dominated 0.075PMS-0.925PZT ceramic obtains great temperature stability with a low variation of resonant frequency below 2.2 % and no variation of non-resonant frequency in the temperature range from 25°C to 175°C. These results make the ceramic as a good candidate for piezoelectric frequency applications that require constant performance within a wide temperature range.

具有良好电性能和温度稳定性的高功率压电陶瓷


铅基Pb(Zr,Ti)O3陶瓷已广泛应用于高功率压电应用，但其在高温下的稳定运行仍然是一个巨大的挑战。在这项工作中，将第三种元素Pb(Mn1/3Sb2/3)O3 (PMS)引入到Pb(Zr0.48Ti0.52)O3 (PZT)中，设计出xPb(Mn1/3Sb2/3)O3-(1- x)Pb(Zr0.48Ti0.52)O3 (PMS-PZT)三元陶瓷通过相图。成功制备了具有同形相界（MPB）结构和均匀晶粒尺寸的陶瓷。分别探讨了陶瓷的介电、铁电和压电性能。 0.075PMS-0.925PZT陶瓷具有优异的压电性能（Qm=1595，kp=0.61，d33=318pC/N，tanδ=0.60%，Tc=300℃），这归因于其MPB结构和钉扎效应缺陷偶极子对域旋转的影响。此外，以T相为主的0.075PMS-0.925PZT陶瓷具有良好的温度稳定性，谐振频率变化低于2.2%，并且在25°C至175°C的温度范围内非谐振频率没有变化。这些结果使陶瓷成为需要在宽温度范围内保持恒定性能的压电频率应用的良好候选者。
