Abstract

The mechanochemical reduction of copper (I and II) oxides by magnesium is studied by means of X-ray phase analysis, electron microscopy, and EDS elemental analysis. The conditions for separating copper particles from other products and protecting copper from oxidation during storage are determined. The sizes of the obtained aggregated particles of reduced copper (~100 nm) are estimated via scanning electron microscopy.
