FIELD: powder metallurgy, namely production of silver powder from aqueous electrolyte solution.
SUBSTANCE: method comprises steps of electrolytic deposition of silver on cathode by action of negative and positive electric current pulses while varying relations of negative and positive pulses of electric current in range (4 -20) : (1 - 5). According to invention deposition of silver is realized on rotary cathode whose axis is arranged in parallel relative to upper surface of electrolyte at revolution number of cathode 7 - 12 rev per min.
EFFECT: enhanced fineness and uniformness of powder particles.
