ABSTRACT
The electrolytic reception of copper powders is the most studied and widely applied
method, but at the implementation of process of electro-deposition, it is difficult to
obtain fine and ultrafine powders.
Surveys have established technological regimes of electrolysis (cathodic current
density, copper and sulfuric acid concentrations, duration of electrolysis, etc.). The
current efficiency depending on the cathode material was studied.
The influences of organic compounds on dendrite-formation, size and grain shape of
obtained copper powder are studied. The nature of organic additives with
different functional groups and structure, affect the nature of grit and dispersion
and the crystal structure of copper deposits, and causes reflexion in
color transition of the deposited powder.
