FIELD: process engineering.SUBSTANCE: invention relates to powder metallurgy, particularly, to production of monodisperse nano-sized powders with preset structures and properties. It can be used in pharmaceutical, food, textile industries, etc. Disperse substances are converted in liquid state by heating at temperature above melting point and below boiling point or that of dissolution in solvent. Obtained fluids are placed in vessel connected with emitted whereto fed is potential that ensures steady-state flow with uniform particles structure. Dispersing is performed in inert gas or fluid at temperature that allows conversion of dispersed flow into solid state. Note here that inert medium is displaced towards dispersed flow at the rate higher than that of particles dancing.EFFECT: monodisperse homogeneous-composition powders.4 cl |
