Thermodynamics of Chemical and Electrochemical Stability of Fe – Ge System Alloys

The standard Gibbs energies of formation of intermatallides Fe6Ge5, FeGe, FeGe2 were estimated. Thermodynamic properties of α- and β- solid metallic solutions of Fe – Ge system and spinel solutions of Fe3O4 – Fe2GeO4 system were determined. The state diagram of Fe – Ge – O system and the potential – рН diagram of Fe – Ge – H2O system at 25ºС were plotted. The thermodynamic features of the corrosion-electrochemical behaviour of Fe – Ge system was discussed
