WebOverall process of aluminum electrolysis is described by the following equation: (2)Al2O3 → 2Al + 1.5O2. Eq. (2) corresponds to electrolysis, in which the anode is non-consumable – inert (based on platinum, ferrite, nitride or other). However, industrial process, the Hall-Héroult process, is based on carbon anodes.
