PROCESS WINNING SILVER POWDER

摘要

FIELD: production of silver powder. SUBSTANCE: process of electrolytic deposition of silver on titanium cathode from aqueous solution of silver nitride with use of pulse current is proposed Electrolysis is conducted with alternating action of current pulses of negative and positive sign. Relation of powers of cathode and anode components is set by amplitudes of negative and positive current pulses, their duration and pulse repetition frequency and is varied as (10-20):(1-5) depending on specified dispersity of silver powder. EFFECT: enhanced efficiency of process and specified dispersity of silver powder.
