Different Ce1-xGdxO(4-x)/2 (x = 0.1; 0.2) samples were analysed by EPR spectroscopy at different temperatures to select the doping level which minimises the occurrence of electronic conductivity. On the base of EPR results analysis, the optimal composition of the nanopowder was selected, and several nanopowders were produced by different chemical processes. The different nanopowders obtained are sintered at high temperature to prepare a high density ceramic materials (rel 96%). Finally, the electrochemical and microstructural properties of those samples were studied.
