    Abstract

    The activities of iron oxide in FetO-SiO2-TiO2-MOx (MOx = CaO, MgO, AlO1.5) quaternary systems in equilibrium with solid iron were measured at 1 673 K. The slag sample was crushed, ground to powder and analyzed. Iron concentration in slags was determined by inductively coupled plasma (ICP) emission spectrometry. Titanium, silicon, aluminum, calcium, and magnesium concentration in slags was determined by X-ray fluorescence (XRF) analysis. Divalent iron (Fe2+) in the slag was determined by the titration method, and the trivalent iron (Fe3+) was calculated by subtracting Fe2+ content from total iron content. Overall, significant results were obtained.
