FIELD: gas-phase technology for producing finely dispersed and ultra dispersed metal powders.
SUBSTANCE: method comprises steps of heating metal till boiling temperature; evaporating it and condensing vapor; feeding metal vapor stream to condenser having shape of its working surface maximally similar to that of contour of vapor stream emission. Condensation and growth of metal particles are realized in zone with thickness approaching to constant thickness. Deposited metal powder is removed continuously along the whole working surface of condenser.
EFFECT: stable fraction size of powder particles, continuous process for producing powder that provides good influence upon strength of equipment.
