Oxygen Permeability of Mixed Conducting Perovskite Lanthanum Gallate-Based Ceramics
The structure, microstructure, electric transport and oxygen permeation properties of (La,Sr)(Ga,Mg,Fe)O3-δ ceramics with perovskite or brownmillerite structures have been studied. Oxygen permeability values of ~0.1 cm3/cm2·min has been revealed at 1000 K for the ceramics studied. The correlation of electroconducting properties of the LaGaO3-based ceramics with perovskite and brownmillerite structures to their oxygen permeability characteristics has been proved.
