The Dielectric, Electric Properties and Microstructure of Ba Mnx Ti1-x O3 (where x = 0.0, 0.01, 0.02, 0.03, 0.04) ceramics have been investigated. The ceramic samples were prepared by Solid-State Reaction Method. The SEM microstructure shows grain size decreased from 192.93 nm down to 167.05 nm. Tetragonal structure was found for samples 0.03% and 0.04% Mn-doped BaTiO3 while others showed pseudo-cubic structure. The Dielectric Constant measurements were executed as a function of temperature. Pure and 0.03% Mndoped ceramics showed improved dielectric constant around Curie temperature region. The temperature dependence of electrical resistivity for all samples were noted acquired that the resistivity changes with the addition of Mn+3 ions in the conduction process accordingly, except pure barium titanate i.e, x=0.0.
