DEVICE TO PRODUCE NANOPARTICLES Russian patent published in 2011 - IPC B01J2/00 B82B3/00 C23C4/00 

FIELD: process engineering.

SUBSTANCE: proposed device may be used in various branches of science and technology. It allows forming nanostructures from nanoparticles with low dispersion of sizes and features high efficiency. Device comprises assembly to form micro-drop flow, micro-drop charging assembly and nanoparticles precipitation assembly. Assembly to form micro-drop flow comprises metal needle and circular cathode inserted into circular groove of dielectric disk with central hole. Micro-drop charging assembly consists of two parts arranged in single dielectric case made up of hollow round cylinder. Nanoparticles precipitation assembly consists of disk cathode with central hole, anode and substrate. Control electrode is arranged around the clearance between assembly to form micro-drop flow and micro-drop charging assembly. Dielectric vase is fitted into solenoid inner chamber.

EFFECT: producing nanostructures from smaller-size nanoparticles with minor dispersion of sizes.
