FIELD: metallurgy.
SUBSTANCE: procedure for production of nano-structured agglomerate of metal cobalt consists in interaction of solutions of cobalt salt of general formula CoX2, where X2 are chlorides, nitrates and/or sulphides with reagents and in reduction at higher temperature. A stabilising agent is introduced into solution before reaction of solutions of cobalt salts with reagents. As a stabilising agent there is used sodium-potassium tartrate. Simultaneously introduced alkali in form of NaOH or KOH are used as reagents at interaction and reduction, while as a reducing agent there is used hydrazine hydrate.
EFFECT: production of new nano structured fractal agglomerates of metal cobalt by simple method under soft process conditions; production of target product of high purity.
