Its concept study started in November 1998 by Samsung Aerospace Industries and Pusan National University. Its design began in February 2002 by Samsung Techwin (previously ...
The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium 's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process ...
Aluminium chlorohydrate. Aluminium chlorohydrate is a group of water-soluble, [ 1] specific aluminium salts having the general formula Al n Cl 3n−m( O H)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification . In water purification, this compound is preferred in some cases because of its high charge, which ...
