Rhombohedral MnTiO3 powder has been synthesized by a high-temperature solid-state reaction method. The formation of single-phase compound is confirmed through XRD, Rietveld refinement and FTIR analysis. The optical band in MnTiO3 obtained from the UV-Vis absorption spectrum has been analyzed. The study of SEM micrographs suggested that the prepared material has good sinter ability and high density with homogeneous grain distribution on the surface and in the bulk. From the impedance and dielectric measurements, the electrical parameters were obtained. It was found that the magnitude of relative dielectric constant (epsilon (r)) was relatively high with low dielectric loss. The study of frequency dependence of AC conductivity suggests that the material obeys Jonscher's universal power law. The variation of DC conductivity with inverse of absolute temperature follows the Arrhenius relation.
