Abstract

Solid solutions of (1−x)(Na0.5Bi0.5TiO3)—x(BaSnO3) (x = 0, 0.15, 0.20, 0.25) are successfully synthesized using conventional solid state reaction route. Formation of solid solutions is confirmed by x‐ray diffraction technique. NBT stabilizes in hexagonal structural form whereas the other end member of solid solution BSN stabilizes in cubic structure. Lattice parameters (a, b) and the unit cell volume increase, whereas c‐parameter decreases with increasing BSN composition. The temperature dependent dielectric constant and dc conductivity also show anomalies at phase transition and show ferroelectric relaxor behavior. Modified Curie‐Weiss law is used to fit the dielectric data that exhibits almost complete diffusion phase transition characteristics.
