Abstract: The viscosity model proposed by Sichen Du and S. Seetharaman et al was applied as a reference to the slag systems without SiO2, based on the constitutional characteristics of Al2O3 slag systems. A new viscosity model was developed for viscosity measurement, focusing on the reaction of aluminium thermit. The feasibility of taking CaO-Al2O3 and CaO-Al2O3-MgO systems as the constituents of the slag systems of CuCr alloy prepared via aluminium thermit-SHS is studied, according to the principle of additive selection in combination with relevant phase diagrams. An analysis was made comparing the experimental measurements with the viscosity values calculated in accordance to the new model. The result shows that it is successful to use the new model to determine the viscosity value of the slag systems which are constituted via the reaction of aluminium thermit.
