Experimental determinations of the viscosities of some Al2O3-CaO-FeO ternary slags were carried out in the temperature range from 1550 to 1764 K using the rotation cylinder method. The measurements were conducted in the composition range from 36 to 48 mass pet Al2O3, 28 to 42 mass pet CaO, and 10 to 33 mass pet FeO. The viscosity was found to show a decreasing trend with the increase of FeO content. Based on the experimental data, the liquidus temperatures of the slags were evaluated using the second derivatives of the activation energies for viscous flow with respect to temperature. The evaluated liquidus temperatures were compared with the results of differential thermal analysis (DTA) on the same slag samples.
