In an effort to interlink the thermo chemical and thermo physical properties of slags, the present workwas undertaken to derive the molar volumes of complex slags from the enthalpies of mixing of thecorresponding slags. As a first step, binary systems of the following oxides were investigated; Al2O3,CaO, FeO, MgO, MnO, and SiO2. An empirical correlation was derived between the enthalpies ofmixing and molar volumes. A comparison of the computed results on the basis of the aboverelationship with the experimental data on molar volumes available in literature shows that theagreement between the calculated results and measured densities is satisfactory in the case of mostof the binary systems, within the limits of experimentally uncertainties. The advantage of the presentapproach is that it would enable prediction of molar volumes of slags that are compatible with thethermodynamic data available.
