Figure 5
Temperature dependence of the unit-cell parameters of CeZrO4 solid solution. Open circles and squares denote the unit-cell parameters 21/2at′ and ct′ of the metastable tetragonal t′ form, respectively. The filled circle denotes the unit-cell parameter ac of the cubic phase. Error bars of standard uncertainties in the Rietveld analysis are smaller than the datum symbols. The solid line is the least-squares fit (quadratic polynomial) and the dashed line is a guide to the eye. |
