Mixtures of ZrO2 (a), Y2O3 (b), Yb2O3 (c) and Al2O3 (d), where the molar fractions (a) = 0.84-0.96, (b) is not >0.16, (c) is not >0.16, and (d) is not >0.04, and pref. either: (a) = 0.88, (b) = 0.06, (c) = 0.04, and (d) = 0.02, or (a) = 0.92, (b) = 0.04, (c) = 0.04, and (d) = 0) show good oxygen conductivity and phase stability at 750-800 degrees C. |
