Crystal structure of metastable tetragonal (t′) CeZrO4 solid solution and relationship between tetragonal cell and pseudo-cubic fluorite (F) cell. Filled and shaded circles denote cations and anions, respectively. Arrows denote the displacement of O atoms along the c axis. Thick dashed lines denote the primitive cell after Teufer (1962), and thin solid lines delineate two pseudo-fluorite cells. |
