ALUMINA
A*lu"mi*na, n. Etym: [L. alumen, aluminis. See Alum.] (Chem.)
Definition: One of the earths, consisting of two parts of aluminium and
three of oxygen, Al2O3.
Note: It is the oxide of the metal aluminium, the base of aluminous
salts, a constituent of a large part of the earthy siliceous
minerals, as the feldspars, micas, scapolites, etc., and the
characterizing ingredient of common clay, in which it exists as an
impure silicate with water, resulting from the decomposition of other
aluminous minerals. In its natural state, it is the mineral corundum.
