A thermodynamic treatment of the corrosion behaviour of Fe in molten Li2SO4−K2SO4 eutectic at 600° is carried out by considering the formation of oxides other than FeO.
Stability diagrams in relation to the redox and acid-baee equilibria in the melt are constructed. Possible cathodic reactions are discussed and the formation of Fe sulphides as corrosion producss is taken into account. Regions of corrosion, immunity and thermodynamic passivity are defined on the assumption of both oxide and sulphide formation.
