FIELD: powder metallurgy, namely production of metal containing nanoparticles.
SUBSTANCE: method comprises steps of interaction of aqueous solution of natural water-soluble arabin
galactan polysaccharide with concentration 1 - 50% as stabilizer and reducer of formed nanoparticles and aqueous solutions with content of metal salts 0.0067 -
2 mmol at presence of ammonium hydroxide or sodium hydroxide; soaking solution for 5 - 60 min at temperature 20 - 90°C; filtering it; precipitating formed filtrate into ethyl alcohol; separating it and drying deposit. It allows produce metal-containing nanoparticles with metal content in range 0.1 - 21.0%.
EFFECT: possibility for producing stable water-soluble metal containing structures, increased life period of nanoparticles.
