PRODUCTION OF ELECTROLYTIC METAL POWDERS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of electrolytic metal powders. It can be used in production of catalysts, electroplating and electronics. Cathodic reduction of metal ions from metal salt solution is carried out in electrolytic cell with rotary cathode and anode or insoluble anode. Cathode is composed of a rod with partially (90-99%) isolated surface. Cathodic reduction is executed at current density from 100 A/dmto origination of electrolyte plasma and metal salt concentration over 100 g/l to saturation.EFFECT: higher process efficiency at high yield and quality of powder.3 ex
