Abstract

• The structural determination of the CeO 2/Gd 2O 3 mixed system is a non-trivial problem because of the close resemblance between the ionic sizes of Ce 4 and Gd 3 and between the crystal structures of CeO 2 and Gd 2O 3. (Ce 1-xGd x)O 2-x/2 powder samples with x ranging between 0 and 1 have been synthesized by coprecipitation of mixed oxalates and subsequent thermal decomposition in air at 1200 °C followed by slow cooling. Synchrotron powder X-ray diffraction data were collected and refined by the Rietveld method. Lattice parameters do not follow Vegards law and no peak splitting has been observed for any composition, meaning that no biphasic regions exist over the whole compositional range. The same hybrid structural model - a proper mixture of the structures of the two pure oxides - was used for the refinements, allowing to account for the data observed. (literal)
