[0002] Electrolytic aluminum is aluminum produced through electrolysis. Modern electrolytic aluminum production utilizes cryolite-alumina molten salt electrolysis. Molten cryolite serves as the solvent, alumina as the solute, carbonite as the anode, and molten aluminum as the cathode. A strong direct current is applied at 950°C-970°C, and an electrochemical reaction occurs at the two electrodes within the electrolytic cell. The resulting metallic aluminum is deposited at the cathode, while the generated oxygen reacts with the anode to produce CO and CO2, which are then discharged. This is known as electrolysis.
