Abstract

Oxygen nonstoichiometry of La0.6Sr0.4Co 1-yFeyO3-δ (y=0.2, 0.8) were measured by high temperature gravimetry and coulometric titration as a function of temperature and oxygen partial pressure. The lattice constant is also observed by HT-XRD as a function of temperature and oxygen partial pressure. The relationship between lattice constant and oxygen deficiency is determined from these results. Almost linear behavior was obtained between them.
