thermodynamic modeling, ferrophosphorus, calcium phosphates, activity, basicityAbstract
The results of thermodynamic analysis of phase equilibrium in Fe - P - C and Ca - P - O systems in temperature - concentration regions corresponding to the conditions for the production of electrothermal phosphorus are presented. The regularities of the change in the activity of the components of the oxide systems under basicity and composition variables are considered. The optimum value of basicity and the effect of Al2O3 MgO additives on the activity of system components have been established.
