FIELD: powder metallurgy, namely processes for producing metallic and oxide nano-particles.
SUBSTANCE: process comprises steps of placing electrodes in chamber with dielectric liquid; realizing pulse electric discharge between them for generating electric arc; measuring spacing between electrodes for fixing its value; creating flow-through motion of dielectric liquid in chamber; measuring temperature of dielectric liquid at inlet and at outlet of chamber; providing preset temperature range of dielectric liquid at inlet and at outlet of chamber due to changing flow rate of said liquid passing through chamber. Temperature difference of dielectric liquid at inlet and outlet of chamber is no more than 7°C. Invention provides increased quantity of nano-particles with fraction size 5 -50 nm.
EFFECT: enhanced quality of nano-particles.
