Abstract: The dissolution equilibrium of magnesium vapour in liguid Fe has been studied in a two-tem- perature-zone furnace at 1600℃ by use of the vapour pressure method.The equilibrium con- stant for the reaction Mg_((g))=[Mg]and the free energy of solution obtained are: K=a_(Mg)/P_(Mg)=0.0236 ΔG°(wt-%)=58300 J/mol

Key words: liquid Fe, Mg, dissolution equilibrium
