摘要：

The structure of active Al/C composite prepared by the mechanochemical method from aluminum and graphite powders (10-30 wt % C) is studied by scanning and transmission electron microscopies, atomic force microscopy, local elemental analysis, X-ray diffraction, as well as by adsorption and sedimentation measurements. It is established that the particles of chemically active Al/C composite represent porous plate-like aggregates with a mean size smaller than 2.5-5 mum and composed of nanocrystalline aluminum blocks with a size of 15-60 nm distributed in a loose amorphous carbon. Single aluminum particles with a size of up to 10 nm are also observed; however, their weight fraction is small.
