DEVICE AND METHOD OF PARTICLES MANUFACTURE Russian patent published in 2017 - IPC B22F9/12 B22F9/28 B01J19/26 

FIELD: chemistry.

SUBSTANCE: method comprises forming a continuous feed gas stream containing saturated material vapor with injecting of mentioned stream through an inlet into the free space of the reaction chamber in the form of a feed stream extending from the inlet and cooling the feed stream in the free space of the reaction chamber to condense solid particles of material from it. Cooling of the supply jet is conducted by means of at least one continuous jet of cooling fluid which is injected into the reaction chamber. The feeding jet is formed by passing a feeding gas stream at a pressure higher than the pressure in the reaction chamber through an injection nozzle installed at the inlet of the reaction chamber with an outlet opening of a rectangular cross section. Cooling fluid crosses the supply jet at an angle of 30-150°. An apparatus for condensing solid particles of a material from the gas phase is also proposed.

EFFECT: obtaining solid particles of micron, submicron or nanometer size with a narrow size distribution.
