Production of alumina

The process of calcination initially involves proton captured by an adjacent hydroxyl, resulting in a water molecule which subsequently diffuses out of the structure. Complete calcination, involving the removal of all the hydroxyls and conversion to alpha alumina, is thus difficult and requires extended times at temperatures above 1000 °C.
