Fine-grained composite material is synthesized from aluminum powder in aqueous solutions of Na-sodium carboxymethyl cellulose. The phase composition of the composite material is determined using X-ray phase analysis and infrared spectroscopy. Aluminum oxyhydroxide (boehmite) stabilized by the polymer material Na-sodium carboxymethyl cellulose is found to be formed during synthesis. The interaction between boehmite and the polymer material is implemented due to intermolecular hydrogen bonds. The formation of 600-nm spherical particles with porous surfaces is revealed by scanning electron microscopy. Unlike traditional methods of producing boehmite at 200–400°С, synthesis occurs at 70–80°С. The prospects of using boehmite for the creation of porous functional materials are shown.
