In this work we have investigated the frequency dependent dielectric properties of PrCrO3 nano-ceramics using alternating current impedance spectroscopy. The material was synthesized by the sol–gel process. The Rietveld refinement of the X-ray diffraction data suggests single phase formation of the material with Pnma space group. The observed structure is substantiated by Raman spectrum of the sample. The ac conductivity follows the power law. The most probable relaxation frequencies at different temperatures were found to obey Arrhenius’ law.

Keywords: Dielectric properties, sol-gel process, X-ray diffraction.
