PROCESS FOR MANUFACTURING FINE MONODISPERSIVE POWDERS OF METAL, SEMICONDUCTOR AND DIELECTRIC MATERIALS Russian patent published in 1996 - IPC

Abstract RU 2063306 C1

FIELD: power metallurgy. SUBSTANCE: in agreement with process supersaturated vapor of matter desired to be manufactured is formed or its mixture with neutral gas in chamber vacuum treated in advance, vapor or its mixture with natural gas is subjected to electromagnetic radiation from external source with preservation of stable thermodynamic characteristics of vapor or mixture, then it is brought of chamber and drops created during condensation are frozen. In some cases non-monodispersive drops of the same matter are added into vapor or mixture of vapor with neutral gas for intensification of condensation process. EFFECT: improved efficiency. 2 cl
