| 摘 要： | 利用传统固熔烧结法研究了Ce掺杂的95KNN-5LiSbO3无铅压电陶瓷（简称KNN-LS）的微观结构、压电性质、老化率和防潮性能。实验结果显示，掺杂CeO2对KNN-LS陶瓷在烧结温度、质量损耗、压电性质和微观结构有特殊的影响规律，本文从微观反应机理上对其做了解释。成功制备出高压电常数（255pC/N）、高致密度（98.1%）、低老化率和高防潮性能的无铅压电陶瓷样品，表明这是一种很有应用潜力的无铅压电材料。

| Abstract: | The effects on microstructure, piezoelectric properties, the aging rate, and the non-deliquescence of 95NKN-5LiSbO3 lead-free piezoceramics (KNN-LS) have been investigated. The experiment results show that a large difference caused by doping CeO2 in the sintering temperature, the mass loss, piezoelectric properties, microstructure appeared. The detailed analysis for the physical mechanism causing these differences is conducted. Samples with high piezoelectric constant (255pC/N), high relative density (98.1%), low aging rate and strong performance against deliquescence are prepared, which indicate that this ceramics is a promising and practical lead-free piezoelectric ceramics. |
