METHOD FOR MANUFACTURING COPPER ELECTROLYTIC POWDER Russian patent published in 2016 - IPC C25C5/02 C25C1/12

Abstract RU 2574185 C1

FIELD: electricity.

SUBSTANCE: invention relates to method for manufacturing copper electrolytic powder with particle size less than 63 mcm with specific surface area within range from 1900 up to 2500 cm²/g and bulk specific gravity less than 0.75 g/cm³. Electrolysis is carried out at copper rod-type cathodes in electrolyte with sulphuric acid at two values of cathodic current density of 2400 and 2800 A/m² with mixing up of the obtained powder fractions and further washing from electrolyte.

EFFECT: reduced specific surface area and bulk specific gravity of the powder.
