EQUILIBRIUM OF Mg-S IN Ni MELTS

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