| Abstract: | The interfacial reactions in the systems of molten Cu-S/CaO-SiO2-Al2O3 and Fe-S /CaO-SiO2-AL2O3 were studied by an A. C. impedance method to clarify the individual kinetic factors concerning the electrode reactions at the interface between the alloys and the slag The total impedance at the iNterfaces was measured. The results obtained were used to determine the individual kinetic factors on electrode reactions between the alloys and the slag, such as electrolyte resistance R., double--layer capacitance Cd, charge transfer resistance Rct, rate constant of desulfurization reaction kf and so on. |
