Abstract

Abstract

A new process of low temperatUre Al₂O₃ suspension electrolysis for producing aluminum in low melting point fluo-chloride system was investigated. Current efficiency (η)expression deduced from experiments on 20~80A electrolysis cell showed that main effects on η are the cell current and the surface of aluminum produced.Increasing cell current and diminishing aluminum surface.can both make η increase. On an electrolysis cell of about 100A capacity with the fine γ-Al₂O₃ (media diam. 1.22μm) and the mixture in which F^-/Cl^- molar ratio was 1 at 750℃,aluminum metal was obtained with 86.3% current efficiency and 11.73 kW. h specific energy consumption.
