Abstract

The attractive properties of ceria, particularly the conductivity and chemical stability, have led to vast research efforts to investigate, characterize and develop such materials. One of the main applications of this ceramic is in the solid oxides fuel cells for intermediate temperatures IT-SOFC. The aim of this work is the preparation and characterization of cubic ceria nanopowders doped with 10 mol % yttria or Scandia. A thermal treatment (calcinations) was applied on the obtained nanopowders, which were consequently investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM) and selected aria electron diffraction (SAED)..
