摘要：

Experimental study was conducted on the equilibrium between molten Fe-Al-S alloys and CaO-Al2O3-CaS slags in a CaS crucible at 1873 K. By application of the Gibbs-Duhem equation, integration techniques were developed to calculate the activities of CaO and Al2O3 from the slag composition and the activities of aluminum and sulfur in the alloy. The free energy of the reaction was also determined as well as the free energies of formation of calcium aluminate compounds CaO·Al2O3(CA), CaO·2Al2O3(CA2), and CaO·6Al2O3(CA6) from their constituent oxides.
