Abstract

Indexed powder patterns are reported for three homogeneous metastable ZrO2-CeO2 solid solution members with high-zirconia [(ZrO2)x mole fraction, x>.84 –.80] and lowzirconia (.60>x>.40) compositions. The primitive cell dimensions are: a = 3.6377(7) Å and c = 5.2394(11) Å at x = 0.84, and a = 3.7205(5) Å and c = 5.3039(7) Å at x = 0.5. Samples with intermediate compositions are heterogeneous. Also reported are powder data for the cubic (fluorite-structure) solution from a sample with x = 0.40 and a slightly different thermal history.
