METHOD OF PRODUCING COBALT NANO-SIZED POWDERS Russian patent published in 2013 - IPC B22F9/16 B82B3/00 B82Y30/00

Abstract RU 2483841 C1

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy. Proposed method comprises thermal decomposition of cobalt-bearing precursor in hydrocarbon oil, its settling, its separation and flushing with hexane. Said cobalt-bearing precursor represents an α-modification of cobalt hydroxide intercalated by sodium dodecyl sulfate. Decomposition is performed for 10-30 hours at 400°C to obtain the product stabilised by carbon film to be dried at 80°C.

EFFECT: ruled out use of aggressive media, inert atmosphere or expensive reagents.
