抄録

Local structures around Ce4+ ions in stabilized tetragonal zirconias with the chemical compositions of 86ZrO2⋅10CeO2⋅4YO1.5 (Ce 10) and 93ZrO2⋅4CeO2⋅3GdO1.5 (Ce 4) were studied by Ce LIII EXAFS (extended X-ray absorption fine structure) analysis. Using CeO2 crystals (Ce-O=2.343Å) as a reference sample, the average Ce-O distances for both Ce 10 and Ce 4 samples were estimated to be 2.32Å and average Ce-cation distances for Ce 10 and Ce 4 samples to be 3.62 and 3.61Å, respectively.
