Abstract

Due to ever-increasing environmental concerns, lead-free piezoceramics have been studied for more than half a century with the purpose of replacing toxic lead-based counterparts. A series of notable breakthroughs have been reported in perovskite-structured lead-free piezoceramics, such as ultra-high piezoelectric and strain properties. By contrast, the development of the temperature stability of lead-free piezoceramics has left far behind and has always been the one of the biggest hindrances for practical applications. In this context, we have summarized the most cutting-edge advances in the temperature stability of perovskite-structured lead-free piezoceramics. We first emphasized the measurement methods of evaluating temperature stability, then summarized the regulating strategies (including phase boundary engineering, texturing, composite ceramics, defect engineering, quenching, and others) used for improving the temperature stability of these lead-free piezoceramics, and addressed the physical mechanisms from a multi-scale view. Finally, we concluded advantages and disadvantages of these strategies and provided our perspective on the challenges and future research of the temperature stability. We hope that this timely review could help the development of the temperature stability of lead-free piezoceramics towards practical applications.

过氧化物结构无铅压电陶瓷的温度稳定性：评估方法、改进策略和未来展望

由于环境问题日益严重，半个多世纪以来，人们一直在研究无铅压电陶瓷，以取代有毒的铅基压电陶瓷。据报道，包晶体结构的无铅压电陶瓷取得了一系列重大突破，例如具有超高的压电和应变特性。相比之下，无铅压电陶瓷在温度稳定性方面的发展却远远落后，一直是实际应用的最大障碍之一。为此，我们总结了包晶体结构无铅压电陶瓷温度稳定性方面的最前沿进展。我们首先强调了评估温度稳定性的测量方法，然后总结了用于提高这些无铅压电陶瓷温度稳定性的调节策略（包括相界工程、制纹、复合陶瓷、缺陷工程、淬火等），并从多尺度的角度探讨了其物理机制。最后，我们总结了这些策略的优缺点，并提出了我们对温度稳定性的挑战和未来研究的看法。我们希望这篇及时的综述能帮助无铅压电陶瓷的温度稳定性向实际应用发展。
