FIELD: metallurgy.
SUBSTANCE: powders of metals and their alloys are produced by electrochemical dissolution of metal anodes. Powder is settled in volume of electrolyte of melted chlorides salts containing chemical compositions able to reduce ions of metals and to regenerate on cathode. The procedure is carried out in salt melt; anodes are made of d-metals or their alloys, for example: Ni, Fe, Cu, Re, Ti, Nb, Mo, W, Pt, Ag and others, steel 20, steel 12X18H10T, nichrome, BT-20 and others. Redox potential of melt is initially set more negative, than electrode potential of produced metal at 100-3000 mV.
EFFECT: essentially expanded functionality of procedure both for choice of produced high and nano disperse metal powder and for its raised output.
