| alumina | <chemistry> One of the earths, consisting of two parts of aluminium and three of oxygen, Al2O3. 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 characterising 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. Origin: L. Alumen, aluminis. See Alum. Source: Websters Dictionary (01 Mar 1998) |

(also called aluminum oxide). A compound of two parts aluminum and three parts oxygen which occurs naturally as corundum. Alumina is the base of aluminous salts, a constituent of feldspars, micas, etc., and the characterizing ingredient of common clay, in which it exists as an impure silicate with water, resulting from the erosion of other aluminous minerals. In a hydrated form it is bauxite. ...
