Prebaked Carbon Anodes are a particular type of consumable electrodes (anodes) designed for aluminium smelting through the Hall-Héroult process. During the smelting process, these carbon anodes are suspended within the electrolysis cell (s) containing the electrolyte, which is primarily aluminium oxide (Al2O3).

Calcined petroleum coke is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity. The primary aluminum industry is the major consumer of calcined petroleum coke, representing approximately 80% of the demand for this carbon material. The balance of calcined coke demand originates from the steel and chemical industries, mostly as recarburizer and the manufacture of titanium dioxide pigment.

Other important additions to electrolytes in current commercial use are aluminum fluoride, calcium fluoride, and lithium fluoride. These fluorides increase the conductivity of the electrolyte and improve the efficiency of the used energy.

Coal tar pitch distilled from by-product coal tar, generated by metallurgical coke ovens, has strategic importance for the aluminum industry. The combination of its binding properties with its high carbon content makes pitch an ideal complement to calcined petroleum coke for the production of carbon anode paste.
