Comparison Of E Traction Of Aluminium


aluminium (US: aluminum)

Extraction and uses of aluminium. Note: You may find all sorts of other formulae given for the product from this reaction.These range from NaAlO 2 (which is a dehydrated form of the one in the equation) to Na 3 Al(OH) 6 (which is a different product altogether).. What you actually get will depend on things like the temperature and the concentration of the sodium hydroxide solution.

The history of aluminium industry

Humankind came across aluminium long before the metal we know today was produced. The Natural History by Pliny the Elder, a Roman scientist, told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver, but too light to be sliver, to Tiberius, the Roman Emperor. Alum, an aluminium-based salt, was used extensively in ancient times.
