摘　　要：由于钙钛矿结构无铅压电陶瓷具有高的压电性能,已成为无铅压电陶瓷研究的热点．本文综述了钙钛矿结构无铅压电陶瓷(Na_(0．5)K_(0.5))NbO_3的研究进展和趋势．重点从添加第二组元、添加助烧剂、取代改性和制备方法四个方面,归纳和分析了(Na_(0．5)K_(0．5))NbO_3基无铅压电陶瓷的研究开发进展,并对(Na_(0.5)K_(0．5))NbO_3基无铅压电陶瓷今后的研究和发展提出一些建议．Lead free piezoelectric ceramics with perovskite structure have attracted considerable attention as new piezoelectric materials because of their good piezoelectric properties. In this paper, The research progress and trend of （Na0.5K0.5）NbO3-based ceramics were summarized and reviewed with emphasizes on the addition of new compositions and sintering aids, ions substitution and processing techniques. The future research works for the developments of （Na0.5K0.5）NbO3- based lead free piezoelectric ceramics were also suggested.
