Ceria based solid electrolyte have been successfully synthesized by solid state route. Precursor powder was milled for 6h, 8h, 12h using ball milling technique with the help of zirconia ball. The calcination was carried out at 600°C to form the required phase formation and confirmed from XRD results. Sintering was carried out at two different techniques such as microwave and conventional sintering for the prepared samples. The results were compared with XRD, SEM and electrical conductivity measurements and reported.
