Anodic behaviour of the Cu82Al8Ni5Fe5 alloy in low-temperature aluminium electrolysis
Source abstract
Abstract
Abstract A Cu 82 Al 8 Ni 5 Fe 5 wt.% alloy was evaluated as an inert anode in the electrolysis of an Al 2 O 3 -saturated, KF 35.6 –NaF 12 –LiF 3 –(AlF 3 ) 49.4 melt (790 °С) for 73 h. It was shown that metal consumption at the alloy/scale interface led to the formation of a ring-like gap that was filled with oxygen-free electrolyte. It was hypothesised that the electrochemical transfer of the alloy components through the gap occurred and the chemical oxidation of the alloy particles after the dissolution-deposition process took place in the scale. It was concluded that the rate of scale formation was governed by the percentage of current that had passed through the gap.
