When aluminum is used as a reducing agent in the production of low-carbon ferrochrome, Al2O3-CaO slag is formed. In thermodynamic simulation of the Al2O3-CaO system by Terra software, the composition of oxide melt is calculated within the approximation of associated solutions. Thermochemical data for the associates in the Al2O3-CaO system are systematized and corrected. The calculated and experimental results for the thermodynamic activities of the individual oxides Al2O3 and CaO are in agreement. © 2013 Allerton Press, Inc.
