Abstract
The CexZr1-xO2 (x=0 similar to1.0) mixed oxides have been prepared by sol-g el method, and their crystal structure investigated by Rietveld analysis. T he phase compositions and cell parameters depend on the CeO2 content. Tetra gonal phase is observed in Ce0.1Zr0.9O2 and Ce0.2Zr0.8O2 samples, while cub ic phase is observed in the compositional range 0.7 less than or equal tox less than or equal to1. Therefore, both cubic and tetragonal phases have be en found in the range 0.3 less than or equal tox less than or equal to0.6; the content of cubic phase increases with increasing x.
