heal.abstract	The carbothermic reduction of alumina has long been recognized as an attractive alternative to the energy intensive Hall-Héroult process used in primary aluminum production. Its implementation however in a viable industrial process has yet to be established due to extensive aluminum volatilization phenomena occurring at the high temperatures needed to achieve the complete reduction of alumina. Such phenomena have been so far attributed primarily to kinetic reasons, such as CO()g bubbling through the produced liquid aluminum melt. In the present work a theoretical thermodynamic study identifies a mechanism, which can explain aluminum vaporization and alumina incomplete reduction as a result of interactions among aluminum species at different oxidation states.	en
