摘要

研究了LiSbO3对(K0.5Na0.5)NbO3陶瓷的结构、微观结构、介电性能、铁电性能和局部压电性能的影响。在不同的固溶体组成中，观察到与离子半径变化相关的单晶胞参数的变化和局部有效d33压电系数值的变化。

Microstructure and Properties of Lead-Free Perovskite Ceramics on the Base of KNN Perovskite

The influence of LiSbO3 on the structure, microstructure, dielectric, ferroelectric and local piezoelectric properties of (K0.5Na0.5)NbO3 ceramics has been studied. Changes in unit cell parameters correlated with ionic radii changes and high effective local d33 piezoelectric coefficient values were observed depending on solid solutions compositions.
