FIELD: chemistry.
SUBSTANCE: invention relates to a composition containing nanometric copper. Dispersion containing nanoparticles of metallic copper, in which at least 10 % of said nanoparticles of metallic copper are monocrystalline particles of metallic copper, average size of secondary particles d50 in the dispersion is in range of 20 to 200 nm, wherein said nanoparticles of metallic copper are at least partially coated with at least one dispersant, and the ratio of concentration of crystalline copper oxide to said nanoparticles of metallic copper is not more than 0.4.
EFFECT: obtaining a stable concentrated dispersion containing monocrystalline particles without agglomeration.
