Abstract : Consideration is given to the thermodynamics of equilibria involving metal solutions, oxide solutions, and atmospheres of known 02 partial pressures. The standard free energy of formation of the oxides of the metals involved are regarded, in one case, as being markedly different (exemplified by the system Mn-Fe-O at 1400K) and, in the other case, as being nearly the same (exempli fied by the system Co-Ni-O at 1700K). Results are presented in the form of ternary phase diagrams.
