PROCESS FOR PRODUCING AGGLOMERATES OF COLLOIDAL METALLIC NANO-PARTICLES

摘要

A process of producing agglomerates of colloidal metallic nano-particles, in which the particle sizes are from 1 nm to 15 ?m, is based on the dispersion of metallic granules in deionized water, combination of large particles nuclei and small nano-particles, which form a shell. The blast erosion dispersion of metallic granules is performed by spark discharges, the nano-particles are electrified in the spark discharges and electrochemical pairs of nano-particles are formed with mainly greatest difference of the values of electrode potentials.
