Synthese et propriétés de conduction ionique des phases Li8−2xCaxCeO6 (0 < x ≤ 0,5) et Li6CaCeO6

Abstract The solid solution Li8−2xCaxCeO6 (0 P 3 C1, a = 10,015 A, c = 10,603 A, c a = 1,058 7 , and Z = 6. This new quaternary phase, which belongs to the same structural family of oxides of the type Li8MO6, either pure or doped with calcium, may be represented by the formula Litetr.6[Ca Ce□]oct.O6. Electrical and structural data are correlated for this compound.
