Abstract

The electrical conductivity of the bulk and grain boundary of oxygen deficient (CaxSr1-x)(Ti0.8Fe0.2)O3-δ (x = 0.14, 0.16, 0.18, and 2.0) polycrystalline specimens were estimated by complex impedance spectroscopy analysis in the domestic frequency ranges from 0.01 Hz to 1 MHz at room temperature. The powder ceramic was synthesized using the sonochemical route. Powder X-ray diffraction of all the samples at 1000 °C shows cubic phase in symmetry. The impedance plots are composed of semicircles followed by warburg impedance for all the compounds. The shrinkage of grains and grain boundaries contribution are increased when Sr2+ ion concentration is increased. This is evident from the observed SEM image of grain morphology of the prepared powders. Frequency dependence of all the electrical parameters are carried out using complex impedance spectroscopy (CIS) analysis. The large dielectric constant is found in CSTFO14 sample in the magnitude order of ∼×105. So, this kind of materials used for the applications of microwave and radio wave communications.
