FIELD: electricity.
SUBSTANCE: metal particles from electrolyte are deposited on substrate till the stage of formation of icosahedral micro- and nano-particles is ended. Then, particles are subject to annealing in neutral medium at temperature of 450-500°C with exposure during 25-60 minutes. Heating to annealing temperature is performed with speed of 5-15°C/min. After annealing the conditions for particle destruction are created. Obtained micro- and nanoparticles are separated from substrate prior to annealing or after annealing.
EFFECT: enlarging specific surface area of obtained powders and improving efficiency of their use.
