Modifying Copper with Alumina during a Mechanically Stimulated Reaction

IR spectroscopy, electron microscopy, and X-ray diffraction analysis, including the application of synchrotron radiation, have been used to study the mechanochemical reduction of copper oxide with aluminum at the stoichiometric ratio of the components and in the presence of an excess of oxide-forming metal and aluminum solid solution in copper as well. The possibility is shown of the mechanochemical reduction of copper oxide with aluminum and aluminum solid solution in copper, which is accompanied by the formation of the Сu/Al 2 O 3 composite structure. To modify copper with alumina, using an aluminum solid solution in copper is preferable.
