无铅压电陶瓷经过20年的半沉寂和10年的半热情研究，现在在某些领域有了明确的应用前景。这模仿了之前从其他技术中消除铅的研究，导致电池中铅的使用受到限制，其他应用中的铅使用减少。对关键器件进行了品质因数分析，并对含铅和无铅压电陶瓷进行了对比。一些现有的应用程序出现，无铅压电陶瓷的使用，可以设想在不久的将来。然而，需要有足够的过渡期以确保可靠性。无铅压电陶瓷在高可靠性、高位移、高频率以及宽温度范围的应用中的应用似乎还很遥远。新的设备进行了概述，其中的品质因数建议跳过含铅压电陶瓷完全。最后对下一步相关研究需求提出了建议。(C)2014爱思唯尔有限公司版权所有。
After twenty years of partly quiet and ten years of partly enthusiastic research into lead-free piezoceramics there are now clear prospects for transfer into applications in some areas. This mimics prior research into eliminating lead from other technologies that resulted in restricted lead use in batteries and dwindling use in other applications. A figure of merit analysis for key devices is presented and used to contrast lead-containing and lead-free piezoceramics. A number of existing applications emerge, where the usage of lead-free piezoceramics may be envisaged in the near future. A sufficient transition period to ensure reliability, however, is required. The use of lead-free piezoceramics for demanding applications with high reliability, displacements and frequency as well as a wide temperature range appears to remain in the distant future. New devices are outlined, where the figure of merit suggests skipping lead-containing piezoceramics altogether. Suggestions for the next pertinent research requirements are provided.
