This paper reports the Strontium and Magnesium doped Ceria solid solutions (Ce0.99Sr0.01O1.995 and Ce0.99M0.01O1.995) were synthesized by solid state reaction method. The doped and un-doped CeO2 samples were sintered at constant Temperature 1400 0C to investigate their density, structural, morphological, electrical properties. The sintered densities of the samples are above 90%. .XRD study reveals the cubic fluorite structure. SEM reveals that the synthesized samples the grains formed are of different size. The grain size depends on sintering temperature and of doping. The EDS spectra show that the samples are free of contaminants.  FTIR study reveals well agreement with Pure CeO2 .A.C. impedance spectroscopy was used to study the ionic conductivity of CeO2, Ce0.99Sr0.01O1.995 and Ce0.99M0.01O1.995 samples. The main aim is to study is (Ce0.99Sr0.01O1.995 and Ce0.99M0.01O1.995 ) compositions showed highest conductivity values than Pure Ceria sample for possible electrolyte for SOFC.
