Processing and study of dielectric and ferroelectric nature of BiFeO3 modified SrBi2Nb2O9

The solid solution of BiFeO3 (BF)–SrBi2Nb2O9 (SBN) prepared at a concentration of 1:1 ratio, shows significant changes in the structure and the physical properties. A solid-state double sintering route was adopted in synthesizing the material. X-ray diffraction (XRD) measurements show a single-phase formation. The dielectric measurements showed anomalies at higher temperatures. Polarization versus electric field measurement indicates the compound consists of ferroelectric ordering. Significant changes are observed when BF is added to SBN in the various physical properties.
