Pr-Gd doped ceria nanopowder particles of the PGDC (Ce0.8Gd0.18Pr0.02O2 – δ) sample were synthesized by a sol-gel process modified using sucrose and pectin. XRD results showed space groupand a cubic structure. The average crystallite size was in the range of 9-13 nm. The average crystallite size value increased with temperature. Raman spectra showed more oxygen vacancies than undoped ceria. The relative density of the sample was 97 %. SEM images clearly showed a denser surface with grains. The electrical conductivity of the PGDC sample was 0.01461 S/cm at 700 C with an activation energy of 0.92 eV.
