Through a fundamental study, the mechanism of metallothermic reduction of Sc2O3in a CaO–CaCl2flux system was determined via a thermochemical equilibrium method, aiming to produce an Al–Sc–Ca alloy (Sc: ∼0.5–3.6 wt%; Ca: ∼0.8–1.8 wt%) at 1273–1623 K. The effect of the oxygen potential on Sc reduction was investigated to establish a general mechanism of Sc reduction. The effect of the CaO activity on the flux and content of Ca in the alloy was evaluated to confirm the role of Ca in the mechanism of metallothermic CaScO2.5reduction. |
