UNIT FOR ELECTRIC PULSE CONTROLLED PRODUCTION OF NANOPARTICLES OF CURRENT-CONDUCTIVE MATERIALS Russian patent published in 2021 - IPC B22F9/14 B82B3/00 B82Y40/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to powder metallurgy and manufacture of nanostructures usable for production of quantum information science, radiophotonics and nanoelectronics equipment, as well as for production of coatings and in additive technology. The unit for electric pulse controlled production of nanoparticles of current-conductive materials comprises charging 3 and discharging 8 circuits. The charging circuit 3 consists of a laboratory autotransformer (LATR) 4, the input terminals 1 and 2 whereof are connected to an alternating voltage power supply network and the output is connected to the primary winding of a high-voltage step-up transformer (HVST) 5, the secondary winding whereof is connected to a high-voltage electric capacitor 7 through protective current-limiting resistors 6. Voltmeters 14 and 15 are provided for monitoring the operating mode at the output of the LATR 4 and HVST 5. The discharging circuit 8, connected in parallel with the high-voltage electric capacitor 7 by means of the output terminals of the latter, consists of an electric spark dispersion reactor 11 filled with a dielectric liquid wherein working dispersible electrodes with terminals 12 and 13, made rotating relative to each other, are submerged, wherein a working interelectrode gap 10 is formed between said electrodes, as well as of a reconfigurable air spark gap 9 with a breakdown voltage greater than the breakdown voltage of the working interelectrode gap 10.

EFFECT: ensured stable generation of an electric spark discharge at low discharge pulse energies of less than 100 mJ and an interelectrode gap of more than 50 mcm in order to produce nanoparticles of conductive materials, close to monodisperse.
