Abstract
Using the Rietveld method, phases of ceria-doped zirconia, calcined at temp eratures of 600 and 900 degrees C, were quantitatively analysed for differe nt concentrations of ceria. The results show that the stabilization of zirc onia depends on the dopant concentration and calcination temperature. Moreo ver, the theoretical calculation using the ab initio Hartree-Fock-Roothaan method indicates that the most stable phases for ceria-stabilized zirconia are cubic or tetragonal, in accordance with experimental results.
