In aluminium reduction cells, an electrochemical reaction occurs between the molten electrolyte film below the aluminium pad and the carbon cathode blocks, leading to the formation of an Al4C3 layer on the cathode blocks. The properties and role of t

This literature review discusses the sludge formation in the Hall–Heroult process. Sludge formation and its transformation into resistive cathodic deposits is one of the focal concerns of the aluminum producers. Sludge formation interacts with the

The presence of resistive sludge on the cathode surface in Hall–Heroult cells can increase the aluminum production costs and reduces cell lifetime. Modern cells with graphitized cathode blocks generally operate satisfactorily but some are exhibitin

Studies on sludge formation in aluminum electrolysis cells are rare and typically do not distinguish the deposits at the center of the cell from those composing the ledge toe because low voltage lost is expected at the center of the cell. However, hi

The efficiency of the Hall-Heroult process is influenced by the formation of solid or solid–liquid deposits on the cathode block surface. These deposits have a high electrical and thermal resistivity. Hence, they disturb the electrical current path

The efficiency of electrolysis cells for aluminum production is reduced when deposits are formed on the cathode block surface. Overfeeding of alumina or excessive heat loss in industrial cells leads to the formation of highly resistive deposits. In t
