In this communication, the effect of a small amount of barium (15%) substitution on structural micro-structural, electrical (dielectric, impedance and conductivity) properties of CaCu3Ti4O12(i.e., Ca0.85Ba0.15Cu3Ti4O12 = CBCTO15) in different experimental conditions is presented. The polycrystalline sample of the material has been prepared by a cost-effective solidstate reaction technique. Rietveld refinement of XRD data has confirmed that the CBCTO15 sample crystallizes in cubic system bearing space group Im3. The surface micrograph depicts the dense packing of grains. The comprehensive studies of dielectric parameters [relative dielectric constant (εr), and loss tangent (tanδ)] are characterized over a wide range of temperature and frequency. The complex impedance and electrical modulus spectroscopy techniques have been employed which postulates the association of various effects (grain, grain boundary, electrode) and shed light on the conduction as well as the relaxation mechanism in the material.
