FIELD: powder metallurgy, possibly production of powder of silver from aqueous solution of electrolyte.
SUBSTANCE: method for producing powdered silver by electrolysis process from aqueous solution of electrolyte containing silver nitrate comprises steps of electric deposition of silver in aqueous solution of silver nitrate (15 - 20g/l) at 20°C onto rotating spherical cathode of stainless steel completely immersed to electrolyte; applying pulse rectangular wave electric current at frequency 0.5 - 1.5 Hz and duty ratio 1.1 - 1.5 to electrolyzer.
EFFECT: enhanced efficiency of process due to increased speed of silver powder deposition without changing its fineness.
