The densities of the selected quaternary CaO-MgO-Al2O3-SiO2 slag with low silica were measured by the Archimedean method in a wide temperature range from 1773 to 1873 K. Nine different slag compositions were chosen based on three different levels of CaO content and three different levels of SiO2 content. wMgO was equal to 7.0%. wCaO were varied from 40.04% to 50.64%, for wSiO2=10.25%-20.70%. The effects of temperature, SiO2 content and optical basicity were studied. It is shown that density decreases approximately linearly with an increase in temperature. Under the same CaO content, the density decreases with increasing of SiO2 content, and increases with optical basicity increasing. Based on the experimental data as the boundary of the homogenous phase region predicated by FACTSAGE software, the mass triangle model is used to calculate the density of selected limited homogenous phase region. The results showed that the mass triangle model works well.
