摘要：

The chemical and physical processes occurring during grinding of copper hydroxocarbonates mixtures with aluminium were studied. A planetary ball mill was used. A thermogravimetry and X-ray powder diffraction method allowed to determine the composition of solid products after mechanical activation. The amount of the Cu-2(OH)(2)CO3 undecomposed and Al2O3. 3H(2)O, CuO, Al2O3, Cu-0, CuxAly alloys and remained Al-0 in the systems is strongly dependent on the duration of grinding and on the proportion of components. The comparative results are presented.
