Abstract In this research article, structural and electrical properties of BaSnO3 (BSn) and BaSeO3 (BSe) substituted (Bi0·5K0.5) TiO3 ceramic (i.e., (1–2x) ((Bi0·5K0.5)TiO3)+xBaSnO3+xBaSeO3 with x = 0, 0.05, 0.10, 0.15 (BKT-BSn-BSe) have been fabricated through high temperature mixed oxide reaction process. The structural, micro structural and electrical characteristics of the parent compound ((Bi0·5K0.5)Ti O3) have significantly been influenced by the substitution of BSn–BSe in it over a large temperature (100–500 °C) and frequency (1 kHz–1 MHz) range. Structural analysis of the compounds, carried out by the room temperature X-ray diffraction (XRD) data, confirms the formation of single phase compounds with tetragonal structure. The surface morphology of the materials, exhibits the homogeneous distribution of grains (with few voids) throughout the surface of the materials. J-E characteristics of the compounds show a NTCR behavior in them. The ferroelectric phenomena of the prepared materials are studied by field dependence of polarization (PE) hysteresis loop study.
