Abstract

The effect of oxygen partial pressure and basicity on the solubility of Sc2O3 in the CaO-CaCl2 flux is studied. As a result, the solubility of Sc2O3 only depends on basicity of the flux and the stable ionic state of which is ScO2.52-. The thermodynamic simulation on the alloy composition of calciothermic reduction is also studied and shows consistency with experimental results.
