Modifying Copper with Alumina
 during a Mechanically Stimulated Reaction

Abstract

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 alumi-num 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 forma-tion of the Сu/Al2O3 composite structure. To modify copper with alumina, using an aluminum solid solution in copper is preferable.
