Long-range crystal structures, local cation/anion environments, and ionic

conduction characteristics of scandia stabilized zirconia with different Sc

compositions were investigated with the help of X-ray diffraction, solid-state

nuclear magnetic resonance, and electrochemical impedance spectroscopy. Both

45Sc and 17O nuclear magnetic resonance analyses were performed. Low ionic

conductivities and high activation energies observed in high-Sc samples at low

temperatures were attributed to defect association and cation ordering.
