Abstract
A method of producing superfine powders of metals includes metal electroerosive dispersing metal granules by passing a pulsed electrical current through electrodes and through chains of metal granules in water in a reactor, creating forced vibration of the reactor with granules and vibration frequency control, wherein the metal pellets are separated into fractions according to their size and metal granules of the fraction with an average grain size D at a distance between electrodes L selected from the relation: L = (5-15)D, preferably L = (8-10)D are subject to electroerosive dispersing, where D - average size of the metallic granules of dispersed fraction.
