Oral Presentations; Poster Presentations ; Christian Rockenhäuser adresses phase formation
and cation interdiffusion of the GdxCe1-xO2-x/2-and SmxCe1-xO2-x/2-material systems
at temperatures ranging from 970 to 1270°C. Diffusion couples with CeO2/Sm2O3 and
CeO2/Gd2O3 interfaces were fabricated for the investigations. The resulting reaction
phases were investigated utilizing transmission electron microscopy (TEM) and allow
conclusions regarding the phase diagrams in the examined temperature range. A miscibility
gap can be ruled out for GdxCe1-xO2-x/2 across the whole composition range. Cation
interdiffusion coefficients were determined
