摘要: Pb(Zr1-xTix)O3 (PZT)由于具有优异的综合性能而成为应用最广泛的压电陶瓷。之前研究工作证明了与直流极化(DCP)和交流极化(ACP)相比,采用交流极化和直流极化相结合的方法能进一步提高弛豫铁电单晶材料的压电性能。本工作报道了直流极化、交流极化和交流极化+直流极化后PZT-4压电陶瓷的介电性能和压电性能,探究了直流极化、交流极化和交流极化+直流极化的最佳极化条件。在最佳交流极化+直流极化条件下, PZT-4 压电陶瓷的压电常数(d33)为350 pC/N,相比直流极化(305 pC/N)、交流极化(320 pC/N)分别提高了15%和9%。交流极化后的PZT-4陶瓷样品的应变值(0.08%)高于进行直流极化样品的(应变值0.05%),表明交流极化可以有效提高PZT-4陶瓷的应变值,但是交流极化后应变曲线的滞后增大不利于器件应用,交流极化对硬性压电陶瓷的影响还需要进一步探讨。

Abstract: Pb(Zr1-xTix)O3(PZT) piezoelectric ceramics have been used extensively due to their comprehensive performance. Compared with direct current poling (DCP) and alternating current poling (ACP) methods, the combining DCP and ACP method can further improve the piezoelectric properties of relaxor-based ferroelectric single crystals. Here, the dielectric and piezoelectric properties of DCP, ACP, and ACP+DCP PZT-4 piezoelectric ceramics. The optimal poling conditions of DCP, ACP, and ACP+DCP were studied. The d33 of ACP+DCP PZT-4 piezoelectric ceramics reported in this paper is 350 pC/N, which is 15% and 9% higher than that of DCP (305 pC/N) and ACP (320 pC/N) samples. The strain value under electric field of the ACP PZT-4 ceramic (0.08%) is higher than that of the DCP sample (0.05%), indicating that ACP can effectively improve the strain value of PZT-4 ceramics. However, the increased hysteresis of the strain curve for ACP sample is not conducive to application. The effect of ACP on hard PZT piezoelectric ceramics needs to be further explored.
