Crystal Structure of Solid Solutions LA1-xRxFeO3 (r=PR, nD)
Complex oxides with perovskite structure RFeO3, where R are rare earth metals, represent an important class of functional materials. RFeO3 compounds are used in thermoelectric devices, solid oxide fuel cells, as membranes for partial oxidation of methane and oxygen cleaning, as catalysts for CO oxidation and decomposition of NOx, and as sensory materials.
