Abstract

In our previous works, we identified the mechanically alloyed Cu65Ni20Fe15 compound as a promising inert anode material for Al production in low temperature (700°C) KF-AIF3 electrolyte. However, further work was required for improving its corrosion resistance. For that purpose, (Cu65 Ni2OFe15)100-xYx materials were prepared by ball milling, consolidated to form dense electrodes and then evaluated as inert anodes for aluminum production. Their morphological, structural and chemical characteristics were studied at different stages of their preparation and after 20 h of electrolysis. The key role played by the element Y on the electrode’s corrosion resistance is highlighted.
