Ferroelectrics with general chemical formula Ba1-xSrxTiO3 (x=0.3,0.5,0.7,0.9) were synthesized by ceramic method and characterized by X-ray diffraction, study of surface morphology by scanning electron microscopy(SEM), porosity variation with different composition of x and same behavior is indicated by SEM micrographs. Dielectric constant studies found with dispersion is due to Maxwell Wagner type interfacial polarization. AC conductivity studies with frequency suggest that small poloron type of conduction mechanism.
