Abstract
Results are reported of a high-temperature XAFS study of the three iro n oxides wustite, FeO, magnetite, Fe3O4, and hematite, Fe2O3. The in-s itu experiments have been performed at temperatures up to 1200 degrees C using oxygen partial pressures appropriate to the stability fields of the three oxides. The spectra provide information on a variety of h igh-temperature properties of these compounds. The present contributio n focuses on the defect structure of nonstoichiometric wustite, FeO.
