Abstract The reaction equilibrium constants and inieraction coefficients of SrO,Ba-O, Sr-S and Ba-S in liquid Fe at 1570℃ have been determined as follows:K_(SrO)=1.897×10~(-7) e_O~(Sr)=-43.8 e_(Sr)~O=-240.0K_(BaO)=8.204×10~(-8) e_O~(Ba)=-98.0 e_(Ba)~O=-841.2K_(SrS)=8.356×10~(-7) e_S~(Sr)=-3.9 e_(Sr)~S=-10.6K_(BaS)=4.083×10~(-7) e_S~(Ba)=-3.5 e_(Ba)~S=-14.9

Key words: equilibrium Sr Ba deoxidisation desulphuration
