  • Kinetics of growth of ultrafine copper powders stabilized by water-soluble polymers in the process of production

    The paper presents the results of studies on the effect of deposition regimes on the properties of electrochemical copper powders. The obtained ultradispersed powders of copper and application of different regimes of electrolysis. The paper presents data on the possibility of obtaining ultrafine copper powders (UDP) in pulsed mode with the addition of polyvinylpyrrolidone (PVP) as a particle growth stabilizer. The influence of the current amplitude and the cathode-anode time ratio is revealed. It is shown that the parameters determining the current wave determine the size of the deposited copper powder particles.
