Abstract — By a method of low-temperature nitrogen adsorption–desorption at the gas/solid interface, the trends in the adsorption and capillary-condensation properties of Al₂O₃/Al composites are studied as a function of the way of conjugate stages, namely, the metal hydrothermal oxidation and the replication of colloidal aluminum hydroxide by surfactants of the anionic, cationic, and non-ionogenic types.
