A comparison is made of the main characteristics of aluminum oxides and hydroxides obtained by mechanochemical oxidation of aluminum powder, both in the initial state and after their heat treatment in the range 150 - 1100 ° C. The conditions for obtaining pseudoboehmite by thermal activation of a mechanochemically oxidized product have been established. The structure, morphology and texture of the pseudoboehmite structure of aluminum hydroxide synthesized from a mechanically oxidized product and aluminum oxides obtained on its basis in the temperature range 450 - 1100 ° C are characterized.
