FIELD: process engineering.SUBSTANCE: invention relates to power metallurgy, particularly, to production of metallic nano-sized powders.Initial powder of metal oxide compounds with particle size not exceeding 50 mcm is fed by carrier gas into reactor of gas discharge plasma. Initial material is heated to temperature exceeding that of oxides sublimation to evaporate metal and to reduce metal oxides in hydrogen flow or its mix with nitrogen or by argon. Metallic powder is isolated on cooling metal vapors by pulsating inert gas flow at gas flow rate of 1·10-1·10m/s.EFFECT: ruled out or minimised agglomeration of condensed nano-sized pareticles.7 cl, 3 ex |
