Abstract
Method and equipment to produce nanopowders of materials based on pure metals, their alloys and chemical compounds of these metals with elements taken from the row of B, C, O and Si, encapsulated into a salt shell selected from the group of NaCl, NaF, LiCl, and LiF or their mixtures, includes independent evaporation by means of electron beam and/or laser radiation sources of the material and alkali metal(s) halogenide and simultaneous deposition of a mixture of their vapor phases on a substrate in a closed pumped-down volume. To achieve the required ratio of vapor flows, a screen with variable cross-section diaphragms is placed between the substrate movable in parallel to the evaporators, and the evaporators, thus allowing an independent regulation of the intensity of the vapor flow coming to the substrate from each of the evaporators.
