摘要:

Pb(Zr,Ti)O3(PZT)陶瓷以其优异的压电、铁电和热释电性能, 在国防、医疗、通信及能源转换等领域发挥着至关重要的作用。然而PZT陶瓷的烧结温度通常超过1200 ℃, 这不仅能源消耗高, 还会造成PbO大量挥发, 使PZT陶瓷偏离化学计量比而影响其电学性能。此外, 压电叠层器件的迅速发展还进一步要求PZT陶瓷能与成本较低的金属电极在低温下进行共烧。针对上述问题, 研究人员对PZT压电陶瓷的低温烧结进行了深入研究, 将PZT陶瓷的烧结温度降低至1000 ℃以下。本文从PZT陶瓷的结构特点、物理性能出发, 对低温烧结技术在PZT陶瓷领域的研究现状进行了综述, 基于低温烧结原理介绍了特种烧结技术(放电等离子体烧结、热压烧结和冷烧结)和引入助烧剂(形成固溶体、液相烧结和过渡液相烧结)的低温烧结现状, 系统总结了上述烧结技术对PZT压电陶瓷微观结构和电学性能的影响规律。针对引入助烧剂导致电学性能劣化的问题及可能的解决途径进行了探讨, 并对PZT陶瓷低温烧结技术的发展趋势进行了展望。

Abstract:

Pb(Zr,Ti)O3 (PZT) ceramics play a crucial role in fields such as national defense, healthcare, communication, and energy conversion due to their excellent piezoelectric, ferroelectric, and pyroelectric properties. However, the sintering temperature of PZT ceramics usually exceeds 1200 ℃, resulting in high energy consumption and a large amount of PbO volatilization. This volatilization disrupts the stoichiometric balance of PZT ceramics, thereby adversely affecting their electrical properties. Moreover, the rapid development of piezoelectric multilayer devices further requires PZT ceramics to be co-sintered with low-cost metal electrodes at low temperatures. To address these challenges, researchers have extensively investigated the low-temperature sintering of PZT piezoelectric ceramics, successfully reducing the sintering temperature of PZT ceramics to below 1000 ℃, which has attracted widespread attention. Starting from the structural characteristics and physical properties of PZT ceramics, this article reviews the current research status of low-temperature sintering technology in the field of PZT ceramics. It mainly introduces the current status of low-temperature sintering techniques, including spark plasma sintering, hot-pressing sintering, cold sintering, as well as the use of sintering aids such as forming solid solutions, liquid-phase sintering, and transient liquid-phase sintering. The influence of these sintering techniques on the microstructure and electrical properties of PZT piezoelectric ceramics is systematically summarized. The issue of electrical performance degradation caused by sintering aids and possible solutions are analyzed. At last, future development trends of low-temperature sintering technologies for PZT ceramic are explored.
