Abstract: The equilibrium of Mg-S in Ni melt was studied by the method of vapour equilibrium in a sealed chamber.At 1530℃ the equilibrium constant of the reaction MgS_(s)=Mg_(Ni)+S_(Ni)and the activity interaction coefficient were determined as K_(MgS)=6.76×10~(-5)and e_S~(Mg)=-9.1.

Key words: Equilibrium constant, Ni, Mg, S, interaction coefficient
