Structural and ferroelectric properties in the solid solution (Ba5TbTi3V7O30)x(BiFeO3)1-x

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 degrees 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.
