Function of additives in electrolytic preparation of copper powder

Hydrometallurgy, 2006
This work investigates the function of additives in the electrolytic preparation of copper powder under various conditions: without additive, with traditional additive, or with polyvinylpyrrolidine (PVP) and sodium polyoxyethylene alkylphenol sulfonate (APES) additives. The influences of the additive on the composition and particle size distribution of

Flowability of Electrolytic Copper Powder

Materials Science Forum, 2005
The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density is higher than 2.2 – 2.3 g/cm3.

Increasing the flowability of electrolytic copper powders

Soviet Powder Metallurgy and Metal Ceramics, 1989
As automatic production lines are being introduced in powder metallurgy, the requirements for materials change, in particular the demand for copper powders of high flowability grows. The currently used electrolytic copper powders have a well-developed dendritic structure, and exhibit virtually no flowability. After mechanical processing not more than 5%

An electrolytic cell for copper powder production

Soviet Powder Metallurgy and Metal Ceramics, 1962
An electrolytic cell design is proposed for copper powder production by cathodic reduction of cupric oxide in N NaOH solution. The reduction, washing out the electrolyte, and drying stages are carried out in a single apparatus, which enables a powder having a low oxide content to be obtained without recourse to stabilizers.
