Mn‐Doped Ba 0.45 Sr 0.55 TiO 3 Ceramic Systems: Dielectric and Impedance Spectroscopic Characterization
Source abstract
Abstract
Mn‐doped Ba 0.45 Sr 0.55 TiO 3 ( x = 0.00, 0.01, 0.02, 0.03, 0.04, 0.05) ceramics were processed by solid‐state route at 1300°C for 6 h in air. Impedance spectroscopic studies showed that the total resistance ( R T ) decreased with the increase in temperature. Samples with x = 0.00, 0.03, and 0.05 exhibited grain boundary contribution to the conduction mechanism. Samples with x = 0.01, 0.02, 0.04 compositions showed both grain (bulk) and grain boundary contributions. Mn substitution proved to be an effective way to optimize the dielectric properties of BST ceramics.
