Oxidation and Reduction
In other words, if aluminum reduces Fe 2 O 3 to form Al 2 O 3 and iron metal, aluminum must be a stronger reducing agent than iron. We can conclude from the fact that aluminum cannot reduce sodium chloride to form sodium metal that the starting materials in this reaction are the weaker oxidizing agent and the weaker reducing agent.

Aluminium
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.It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air.

Mechanism of Aluminum Carbide Formation in Aluminum
The formation and dissolution of aluminum carbide is considered the primary factor affecting the life of aluminum electrolysis cells. Herein, the characteristics of sodium-graphite intercalation compounds (Na-GICs) were measured and the formation mechanism of 4

Defluorination of spent pot lining from aluminum
2020/6/11. Introduction Spent pot lining (SPL) is a hazardous waste produced during the Hall−Heroult process in the electrolytic aluminum industry (Xiao et al., 2018a).During the electrolytic reduction process, the electrolyte (e.g., Na 3 AlF 6, AlF 3, CaF 2, LiF), molten aluminum, and other corrosive substances continuously infiltrate into the carbonaceous lining (Chauke and Craig, 2013), causing
