Abstract
EMF measurements of solid electrolyte galvanic cells at temperatures r anging within 1073-1273 K supplied more information about the thermody namics of the reaction of LaFeO3 formation. Gibbs energy, enthalpy, an d entropy of LaFeO3 formation, as well as equilibrium oxygen pressures for the orthoferrite dissociation, were determined as functions of te mperature.
