FIELD: process engineering.
SUBSTANCE: invention relates to production of metal nano-sized powders. Proposed method comprises heating initial metal in inert gas flow to initial metal evaporation temperature and extracting metal powder from said flow at temperature lower than that of initial metal fusion point. Initial metal is heated by electron beam with energy of 0.4-3.0 MeV and power not lower than 200 kW at pressure approximating to atmospheric pressure and inert gas flow rate making 0.5-25000 l/min.
EFFECT: industrial production of high-purity metal nanopowders.
