METHOD OF PRODUCING COBALT NANO-SIZED POWDERS

摘要

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 ?-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.6 dwg, 4 ex
