Abstract

The standard Gibbs energies of formation of Mn7C3, Mn5C2, Mn15C4, and Mn23C6 have been obtained from emf measurements using galvanic cells of the type (-)Mn, MnF2, CaF2//CaF2//CaF2, MnF2, ‘Mn-C’(+) The measurements have been carried out in the temperature range 909 to 1247 K. In the case of measurements with Mn-C alloy containing 12.9 wt pct C (Mn7C3-C two-phase region at room temperature), the slope change in the emf-temperature curve at 1181 K suggests the formation of a hitherto unidentified phase above this temperature.
