Abstract: The BSCF, Barium Strontium Cobalt Iron Titanate{Ba0.5Sr0.5 (CO0.8 Fe0.2)1-x TixO3-δ,}[Where δis the deficiency of oxygen & x is various compositions ], powders have been synthesized by sol-Gel process using nitrate based powdered chemicals for SOFC applications as these powders are more useful for Cathodes and anodes for SOFCs since these powders are considered to be more promising cathode materials for SOFC. Ionic conduction, Adsorption and desorption rates are the major processes that control the electrode reactions. They contribute to the over potential .To obtain the low potential cathode materials suitable for the electrolytes, SOL-GEL method is used and nano powders are prepared. The Chelating agent used is Acetic acid, Ethylene glycol & Ammonia as dispersant. These powders were kept for calcinations at 9000C for 16 hr and at 11000C for about 6 hr in crucibles of high alumina in furnace .These were characterized by XRD, SEM with EDAX, Densities, TGA and conductivities.XRD results proved the formation of Perovskite phase at all calcinations temperatures and the crystallite sizes were found to be 94.49nm, 103.9nm ,295.29 nm. From SEM, it is found that for some samples, there is presence of extreme porous particles present in nano sizes and conductivities, densities are studied
