Abstract A study of the dissolution equilibrium of Mg vapour in liquid Fe was carriedout at 1873 K in a two-temperature-zone furnace by use of the vapour pressure method. Theequilibrium constant for the reaction Mg(g)=[Mg] and free energy of solution obtained are:K=a_(Mg) /p_(Mg) =0.0236△G°(wt--%)=58300 J/mol

Key words: liquid Fe Mg dissolution equilibrium
