Of all the bauxite mined about 95% is converted to alumina. World production of alumina is about 50 Mt/ year. The majority (about 90%) of the alumina is used for the production of aluminum most of the rest goes into nonmetal uses such as specialty aluminas. It is this latter quantity that is of interest to us in ceramics. The primary suppliers of specialty aluminas in the United States are Alcoa, Alcan, Aluchem, LaRoche, and Reynolds.
