Conclusions The process of galvanodynamically producing copper powder can be intensified by employing the procedure of bubbling air through the near-anode space to achieve an increase in the limit current density for a laminar electrolyte flow regime about the cathode surface. The use of this bubbling procedure makes it possible to produce a powder with an elevated bulk density whose magnitude is determined by the ratio of the discharge current density for the metals at the tips of the dendrites relative to the limit diffusion current density. With an increase in this parameter the bulk density of the powder is reduced. Industrial tests of the galvanodynamic method for production of copper powder involving the use of the air-bubbling method show the possibility of producing a powder with a uniform copper composition and a bulk density in the electrolysis stage on the order of 2 g/cm 3.
