METHOD FOR PRODUCTION OF METAL OR SEMICONDUCTOR NANOPARTICLES DEPOSITED ON CARRIER Russian patent published in 2010 - IPC B22F9/14 B82B3/00 C23C4/00 

FIELD: technological processes.

SUBSTANCE: invention is related to methods for production of nanoparticles and may be used in processes of application of highly efficient catalytic nanocoatings. Method includes melting and dispersion of melt material, supply of produced liquid drops of this material in plasma, cooling of liquid nanoparticles formed in plasma till they harden, and depositing of produced hard nanoparticles onto carrier. At the same time values of plasma parametres are selected based on the following ratios: where T_e is electronic temperature of plasma, eV, n_e is electronic density of plasma, m^-3, α is coefficient of surface tension of dispersed melt material, n/m, R and r - maximum and minimum values of liquid drops radius, m; L is specific size of plasma, m.

EFFECT: possibility to use independent ratios for selection of plasma parametres and accounting of dispersed material properties, increased efficiency of nanoparticles production process.
