Abstract Main features of the formation of porous composites by hydrothermal treatment of powdered aluminium were studied by scanning electron microscopy, TEM, XPD, IR spectroscopy of lattice modes, and thermal analysis. Hydrothermal oxidation of aluminium was shown to proceedvia generation and subsequent oriented growth of well-crystallized boehmite platelets, whose subsequent dehydration yields γ-alumina. Relation between the degree of the metal oxidation and specific surface area/crushing strength of the composites was analyzed.
