Figure 4
Schematic view of (a) Y1O6 and (b) Y2O6 polyhedra in C-type Y2O3, (c) ZrO7 polyhedron in monoclinic ZrO2, (d) and (e) two YO6, and (f) ZrO7 local structure models in Y-CSZ with bond distances given in Å. The models (d), (e) and (f) in Y-CSZ geometrically correspond to (a), (b) and (c), respectively. The insets show schematic atom displacements from the cubic coordination polyhedra. Vo is an O-atom vacancy. O atoms near the back face of the cube are shaded darker. |
