Figure B7 summarizes the thermal transformations of the components of bauxite. These transformations are dependent upon the particle size, the rate of heating and the vapor pressure above the bauxite. In principle if gibbsite is heated it alters structure to form Chi-alumina, then kappa-alumina and at temperatures above 1100 °C alpha-alumina.
