Abstract The solid solution of (Ba5TbTi3V7O30)x(BiFeO3)1-x has been synthesized by solid-state reaction technique with different x values. XRD (X-Ray Diffractogram) study confirms the formation of single-phase compound for x = 1. Grain morphology has been studied by Scanning electron microscope (SEM: JOEL-IT300). By Impedance Analyzer (HIOKI-IM3536) dielectric properties such as dielectric constant and loss tangent have been measured in a wide temperature range (RT-500° C) and also with a wide range of frequency(1 kHz-1MHz). This dielectric result confirms the Ferroelectric nature of all the samples and with increasing content of BiFeO3, the dielectric constant decreases.

固溶体中的结构和铁电特性 (Ba5TbTi3V7O30)x(BiFeO3)1-x

摘要 采用固相反应技术合成了不同x值的(Ba5TbTi3V7O30)x(BiFeO3)1-x固溶体。XRD（X 射线衍射图）研究证实了 x = 1 的单相化合物的形成。通过扫描电子显微镜（SEM：JOEL-IT300）研究了晶粒形态。通过阻抗分析仪（HIOKI-IM3536），可在宽温度范围（RT-500°C）和宽频率范围（1 kHz-1MHz）下测量介电常数和损耗角正切等介电特性。该介电结果证实了所有样品的铁电性质，并且随着 BiFeO3 含量的增加，介电常数降低。
