Abstract

As an interconnecter of solid oxide fuel cell, La_1-xCa_xCro₃(x = 0.0-0.5) were prepared by sol-gel method. The crystal structures of La_1-xCa_xCro₃ at room temperature are the orthorhombic perovskite GdFeO₃-type. XPS analysis indicates that chrome ions are in different valence state. The introduction of Ca²⁺ into the lattice induces the oxidation of Cr³⁺ to Cr⁶⁺. With x increasing, the amount of Cr⁶⁺ increases. The present of the more Cr⁶⁺ is one of the important factors that effect electric conductivity of La_1-xCa_xCro₃.
