| Abstract: | 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 Cu2(OH)2CO3 undecomposed andAl2O3⋅3H2O, CuO, Al2O3, Cu0, CuxAly alloys and remained Al0 in the systems is strongly dependent on the duration of grinding and on the proportion of components.
The comparative results are presented.
