Structure and Conductivity of Perovskite-Type LnFexCO1-xO3

摘要：

The perovskite-type solid oxides (ABO<,3>) were a novel kind of functional material with superior properties and have found wide application. A series of nanocrystalline mixed oxides LnFe<,x>Co<,1-x>O<,3> (Ln=La, Pr, Sm, Dy, Er) were prepared by sol-gel method. Several aspects of the perovskite type LnFe <,x>Co<,1-x>O<,3>, such as crystal defects, oxygen ion vacancy, the tolerance factor of the ABO<,3>, col size, and the bond energy of chemical bond, searching for the relationship between the conductivity and structure of the perovskite type LnFe<,x>Co<,1-x>O <,3>, hoping to find some regularities in theory, and providing some helps for composing new type of electricity materials.
