Critical assessment and thermodynamic modeling of the Cu-As system
Source abstract
Abstract
Thermodynamic assessment and modeling of the Cu-As system are presented. The experimental dataset includes phase equilibrium data, activity measurements, heat contents, enthalpies of formation and mixing. The liquid phase and two non-stoichiometric copper arsenide solid solutions are developed within the framework of the Modified Quasichemical Model (MQM) in pair approximation. It is demonstrated that the unconventional choice of model for solid solution phases is beneficial for this particular system. The resulting set of model parameters will be a part of a large multicomponent thermodynamic database. It is aimed for predictions of phase equilibria, heat balance and distribution of elements in arsenic-containing chemical systems in pyrometallurgical copper and lead industrial operations.
