摘要
综述了KNN基无铅压电材料的研究进展。主要归纳了掺杂改性,添加助烧剂,添加第二组元,K/Na比的调整和制备工艺等方面的影响,并对其研究和发展进行了展望。
In the present paper, the newest research progress of KNN based lead-free piezoelectric ceramics is summarized. Doping, addition of sintering aids, changing of the ratio of K to Na and preparation methods are discussed, together with the development and prospects of KNN-based lead-free piezoelectric ceramics.
