Study Of Phase Transition In NanostructuredZrO_2-CeO_2 Solid Solutions By SynchrotronRadiation

摘要

In this work we studied the tetragonal to cubic (t-c) phase transition as function of temperature in compositionally homogeneous ZrO_2-CeO_2 powders by synchrotron radiation X-ray diffraction (SR-XRD). Transitions are correlated with changes in the local order of the second coordination shell of Zr atom, studied by EXAFS.
