Refers to methods for production of nanopowders of different materials. A method for production of nanopowders, including evaporation of a target by a pulsed electron beam, condensation of the vapor of the material in a low-pressure gas, and deposition of nanopowders on a cold disk. A device for realization of the method consists of a pulsed electron beam source, a beam guidance and focusing system, a gas pressure differential system, an evaporation chamber, a target, and a powder collecting system, which is a cooled rotating disk with a scraper. By this method, it is possible to produce nanopowders of the oxide with the characteristic size of 3-5 nm and nanopowder agglomerates with the characteristic size of 20-200 nm having the specific surface of up to 180 m2/g at the production rate of up to 12 g/h and the specific energy consumption of less than 120 Wh/g.
