The Redox Equilibrium in Wüstite and Solid Solutions of Wüstite and Magnesium Oxide

摘要: Measurements have been carried out on the equilibrium between ferrous and ferric iron in wustite containing various amounts of magnesium oxide, at partial oxygen pressures 1400 °C. These data, together with data Darken Gurry [2] for pure wustite, are used a discussion applicability mass action law redox equilibrium. Some quantitative formulas derived connection composition pressure magnesiowustite. The calculations strongly indicate that Fe(III) ions associated vacancies
