采用常规方法合成了0.90Pb（Zr0.48Ti0.52）O3-0.05Pb（Mn 1/3Sb 2/3）O3-0.05Pb（Zn 1/3 Nb 2/3）O3（0.90PZT-0.05PMS-0.05PZN）四元系压电陶瓷，并采用CuO降低了其烧结温度。晶体结构，微观形貌，和电气性能进行了研究，在CuO含量。结果表明，1.0wt%的CuO添加显著改善了0.90PZT-0.05PMS-0.05PZN陶瓷的烧结性，将烧结温度降低至900 °C，并保持适度的电性能：d33=306 pC/N，Qm=997，kp= 53.6%，tan δ= 0.50%，和ε 33 T/ε0=1350。低温烧结行为可以用CuO在烧结过程中形成过渡液相来解释。此外，原始陶瓷粉末的差热分析（DTA）曲线中约950 °C处的吸热峰提供了非晶相的进一步证据。为了获得更好的压电性能，选择La 2 O3作为0.90PZT-0.05PMS-0.05PZN +1.0wt%CuO系统的施主掺杂剂。我们的研究表明，La 2 O3是非常有效的改善压电性能，显着增加d33和kp没有降低Qm。最后，添加0.5wt%La2O3的0.90PZT-0.05PMS-0.05PZN +1.0wt%CuO陶瓷具有优异的电学性能：d33=355 pC/N，Qm=936，kp= 58.4%，tan δ= 0.32%，ε 33 T/ε0=1590，非常适合于多层压电陶瓷驱动器。
A quaternary 0.90Pb(Zr0.48Ti0.52)O3–0.05Pb(Mn1/3Sb2/3)O3–0.05Pb(Zn1/3Nb2/3)O3 (0.90PZT–0.05PMS–0.05PZN) piezoelectric ceramic was synthesized by a conventional method, and CuO was adopted to lower its sintering temperature. The crystal structure, micromorphology, and electrical properties were studied in terms of CuO content. The results indicate that 1.0 wt % CuO addition significantly improves the sinterability of 0.90PZT–0.05PMS–0.05PZN ceramics, lowering the sintering temperature to 900 °C and maintaining moderate electrical properties: d33=306 pC/N, Qm=997, kp=53.6%, tan δ=0.50%, and ε33T/ε0=1350. The low-temperature sintering behavior could be explained by the formation of a transient liquid phase by CuO during sintering. Moreover, the endothermic peak at about 950 °C in the differential thermal analysis (DTA) curve of the raw ceramic powder provides further evidence of an amorphous phase. To obtain better piezoelectric properties, La2O3 was selected as the donor dopant for the 0.90PZT–0.05PMS–0.05PZN + 1.0 wt % CuO system. Our study demonstrates that La2O3 is very effective in improving piezoelectric properties, markedly increasing d33 and kp without decreasing Qm. Finally, 0.5 wt % La2O3 added 0.90PZT–0.05PMS–0.05PZN + 1.0 wt % CuO ceramics show excellent electrical properties: d33=355 pC/N, Qm=936, kp=58.4%, tan δ=0.32%, and ε33T/ε0=1590, which are quite suitable for multilayer piezoelectric ceramic actuators.
