Abstract We have investigated the electrical behaviour of MnO2 modified (x = 0.00, 0.04, 0.08, 0.12 mol) (Ca0.4Sr0.6)Bi4Ti4O15 (CSBT-xMn) ceramics prepared using a conventional solid-state reaction method. The structural analysis confirmed no considerable… Click to show full abstract

Abstract We have investigated the electrical behaviour of MnO2 modified (x = 0.00, 0.04, 0.08, 0.12 mol) (Ca0.4Sr0.6)Bi4Ti4O15 (CSBT-xMn) ceramics prepared using a conventional solid-state reaction method. The structural analysis confirmed no considerable changes in the crystal structure. However, an improvement in relative density along with dense microstructure was observed due to Mn addition. A temperature-dependent dielectric study showed a significantly low dissipation factor (
