Transformations of hydrargillite γ-Al(OH)3 during mechanochemical activation in various grinding mills and further calcination of activated samples at 200-1300°C were studied. The effects of mechano-chemical activation and additions of iron(III) oxide compounds on the temperature of corundum formation and on its crystal size distribution were studied.
