摘要

本研究采用常规固相反应法制备了环境友好型无铅$($ (Na0.5Bi0.5)0.45Ba0.40Sr0.15TiO3(NB-BST)陶瓷。在950°C、1000°C和1050°C的烧结温度下，研究了陶瓷的结构和电性能。晶粒尺寸为~0.267 ~ 0.447µm。结构分析显示具有pm-3m空间群的立方对称性。发现NB-BST陶瓷的P-E环形状与烧结温度密切相关

Lead-free (Na0.5Bi0.5)0.45Ba0.40Sr0.15TiO3ceramic: Synthesis, structure and polarization response

In the present study, environmental-friendly lead-free $($ (Na0.5Bi0.5)0.45Ba0.40Sr0.15TiO3(NB-BST) ceramics were prepared by conventional solid-state reaction route. The structural and electrical properties of the ceramics were investigated for 950°C, 1000°C, and 1050°C sintering temperatures. Grain size was found to be ~0.267-0.447 µm. The structural analysis revealed cubic symmetry with a pm-3m space group. P-E loop shape of NB-BST ceramic was found to be strongly dependent on sintering temperature
