Notes:
One of the methods for powder synthesis that is both cost and time effective is the selfpropagatingroom temperature synthesis. We applied this method to synthesize rare earth dopedceria nanopowders. Since they exhibit very high ionic conductivity at intermediate temperaturesthese compositions are attractive for a new generation of nanostructured ceramics applicable insolid oxide fuel cells as electrolytes. In this paper we paid our attention to the reaction based onmethathetical pathway, whereby solid solution nanopowders of rare earth elements with ceria wereobtained at room temperature. Compositions of Ce1-xRexO2-δ (Re = Y , Nd) were synthesized with xranging from 0 to 0.20. The reaction course is discussed and the properties of the obtained powdersare presented
