It has been established that the influence exerted by organic additions on the formation of finely divided deposits and the properties of resultant powders are determined mainly by the specific action of the additions on the kinetics of metal discharge and by the diffusion of the ions being discharged in the electrode surface. Organic additions, whose use offers an effective means of influencing the electrocrystallization of loose cathodic copper deposits, enable powders to be obtained having different processing and physical properties. The introduction into an electrolyte of additions affecting the diffusion of the ions being discharged reduces the particle size, apparent density, and flowability of the powder and produces a more dendritic particle structure. Additions inhibiting the discharge of metal ions promote the formation of coarser powders of increased apparent density and flowability and simpler particle shape. |
