Abstract
Thermodynamic properties of the Cr-C system were determined by means of emf measurements using a single crystal of calcium fluoride as a solid electrolyte. The constructions of fluorine concentration cells were

Using the emf values and its temperature dependences of the above cells between 880° and 1098°K, the standard free energies and enthalpies of formation of Cr3C2 and Cr7C3 were obtained as
