  1. 1.

    It is demonstrated that, in the electrocrystallization of copper powder, the influence of CuS as well as that of Cu2S must be taken into account.

  2. 2.

    The mode of action of copper sulfides is based on the colloidal-adsorption effect of these compounds on the formation of loose cathode copper deposits.

  3. 3.

    With rise in the concentration of sulfide ions in the electrolyte, the particle size of the copper powder decreases, while the extent of dendritic development and the specific surface area of the powder pass through a maximum at CS2− = 5 · 10−5 g-ion/liter.
