Paper Title:
Low-Temperature Combustion Synthesis and Characterization of Ce1-xPrxO2-δ Solid Solutions
  Abstract

Pr2O3-doped ceria nanopowders were synthesized by a nitrate-citrate combustion process. This route is based on the gelling of nitrate solutions by the addition of citric acid and ammonium hydroxide, followed by an intense combustion process due to an exothermic redox reaction between nitrate and citrate ions. XRD analysis showed that no impurity were observed up to x=0.3 in Ce1-xPrxO2-δ systems. The influence of ignition temperature on the characteristics of the powders was studied. The change of the crystal structure with the content of doped Pr was investigated. The highest ionic conductivity, σ600°C=2.45×10-3S/cm, was found for the composition of x=0.15.
