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.
