Corundum: A compound of elements

Corundum is a mineral consisting of aluminum oxide with a chemical formula Al2O3. Aluminum is the most abundant metallic material in the crust of the earth; only the oxygen and silicon are found in greater abbundance. Aluminum is never found as a free metal. It is commonly found as aluminum silicate or as a silicate of aluminum mixed with other metals such as sodium, potassium, iron, calcium, and magnesium. These silicates are not useful ores and it is chemically difficult, and therefore an expensive process, to get aluminum from them. Bauxite, an impure hydrated aluminum oxide, is the commercial source of aluminum and its compounds. Oxygen makes up 21 percent by volume or 23.15 percent by weight of the atmosphere; 85.8 percent by weight of the oceans (88.8 percent of pure water is oxygen); and, as a material of most rocks and minerals, 46.7 percent by weight of the solid crust of the earth. Oxygen accounts for 60 percent of the human body. It is a important for all living tissues; almost all plants and animals, including all humans, require oxygen, in the free or combined state, to maintain life. Alumina or Aluminum Oxide Al2O3 , is an oxide found in nature as the mineral corundum, Al2O3; diaspore, Al2O3+H 2O; gibbsite, Al2O3+3H2O; and most commonly, bauxite, an impure form of gibbsite. It is the only oxide formed by the metal aluminum. The precious stones ruby and sapphire are composed of corundum...
