PRODUCING MOULDED METAL PARTICLES AND USE THEREOF Russian patent published in 2015 - IPC B01J13/00 B22F9/24 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to moulded particles of transition metals, particularly in the form of a dispersion in an aqueous and/or organic medium, to production thereof and to use thereof as an agent which absorbs infrared radiation, an infrared curing agent for coatings, an additive in conducting compositions, printing ink and coating compositions, an antimicrobial agent or for detecting organic and/or inorganic compounds. A dispersion of transition metal nanoparticles is obtained in the form of nanoplates. The metal is selected from a group consisting of Cu, Ag, Au, Zn, Cd, Ti, Cr, Mn, Fe, Co, Ni, Ru, Rh, Pd, Os, Ir and Pt. An aqueous solution of a reducing agent is added to the cooled aqueous mixture containing a transition metal salt and a polymer dispersing agent. The obtained colloidal dispersion is treated with peroxide. In another version of producing a dispersion of nanoparticles, water is partially replaced with an organic medium. The dispersion substantially consists of the obtained transition metal particles and a thermoplastic polymer or a cross-linkable polymer.

EFFECT: invention relates to dispersions containing said moulded particles and aqueous and/or organic media, such as a thermoplastic or cross-linkable polymer, as well as antimicrobial compositions and products.
