“…In contrast to La 2 Ce 2 O 7 , La 2 Zr 2 O 7 have two additional weak peaks at 2u % 37 and 45 (using Cu Ka as radiation resource) in its XRD patterns. These two peaks could help us distinguish the fluorite and pyrochlore structure [20]. The observation of the defect-fluorite phase throughout the homogeneity range could be attributed to the range of r A /r B (r A and r B are the ionic radii of the A and B cations, respectively) ratio.…”

“…Ln 2 Zr 2 O 7 exhibits a special crystal structure with a variety of properties such as relatively high melting point, high thermal expansion coefficient, high thermal stability, high oxide-ion conductivity and high catalytic activity [6][7][8][9]. The pyrochlore structure (space group Fd3m) and the defect fluorite structure (space group Fm3m) are two different kinds of crystal structures for Ln 2 Zr 2 O 7 [10].…”
