Abstract: Thermodynamic properties of the Fe-V-Ce liquid solutions have been studied in the tempera- ture range of 1550-1650℃. The temperature dependences of the equilibrium constants of re- action Ce_2O_2S = 2[Ce]+2[O]+[S] and the standard free energy of formation of Ce_2O_2S have been obtained. The temperature dependences of the interaction coefficients e_v~(Ce) and e_(Ce)~v have also been determined.

Key words: Fe-V-Ce system, activity, interaction coefficient
