Aluminum oxide is a white powder. Raw aluminum is liquid aluminum extracted during the electrolysis process without precipitation treatment. In the cast aluminum ingot model, raw aluminum can be turned into aluminum ingots through cooling processing.
Therefore, alumina is the raw material for molten aluminum, electrolytic aluminum is the process, raw aluminum is the molten aluminum in the electrolysis process, and aluminum ingots are aluminum products that can ultimately be sold on the market.
Electrolytic aluminum is aluminum obtained through electrolysis. The modern electrolytic aluminum industry uses cryolite-alumina molten salt electrolysis. Molten cryolite is the solvent, aluminum oxide is the solute, the carbon body is the anode, and the aluminum liquid is the cathode. After applying strong direct current, the two poles in the electrolytic cell undergo electrochemical reaction at 950 ~ 970 for electrolysis.
