Thermodynamic assessment of the CaO–Al2O3–Sc2O3 ternary system
Source abstract
Abstract
Sustainable utilization of rare earth elements (REEs) in Baotou Steel tailings has recently attracted significant interest in industries and research community. However, few thermodynamic data has been reported for REE systems, which greatly limits the sustainable utilization of Sc2O3 in Baotou Steel tailings. Therefore, based on the experimental phase equilibria and thermodynamic data, the thermodynamic parameters of CaO–Al2O3–Sc2O3 system over the whole composition range are optimized with CALPHAD approach. The modified quasichemical model (MQM) is used to describe the liquid phase. The solid phases are treated as stoichiometric compounds. A set of self-consistent thermodynamic functions for all phases in the CaO–Al2O3–Sc2O3 system are obtained. The available phase equilibria and thermodynamic data are reproduced well within experimental error limits.
