Abstract
The thermodynamic properties of the higher manganese carbide in Mn7C3 have been determined by measuring the emf of the high-temperature galvanic cells
In the range 1000–1150°K the isobar-isothermal potential of the formation of the carbide is represented by the equation
The standard heats and entropies of formation are, respectively, -19.8 ± 1.2 kcal/mole and 1.1 ± 0.4 cal/deg • mole.
