Aluminium - Wikipedia

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and ...

Aluminum Production - an overview | ScienceDirect Topics

Feb 05, 2011· The amount of aluminum predicted by Faraday''s law is never obtained in practice. In parallel with the aluminum production reaction, a quantity of metal made at the cathode dissolves into the electrolyte at the boundary layer at the bath–metal interface and is transported to the reaction zone where it is oxidized, recognized in the industry as the back reaction, by CO 2 gas forming CO gas ...
