HISTORY,
BACKGROUND & USES:
Discovered in 1827 by Friedrich Wöhler. It occurs in a variety of silicate rocks, mainly mica, and
feldspar. These rocks disintegrate by a process called weathering,
in which moisture and carbon dioxide form clay, and ultimately
aluminum oxide. The principal aluminum ore, bauxite, is formed
by this process. Aluminum also occurs as cryolite. Because of
its light weight, resistance to corrosion and tensile strength,
it is excellent for the construction of the structure of a building.
Because it can easily be rolled into sheets, much is used for
aluminum foil. Aluminum powder is sometimes used in certain types
of paint.
