FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, methods of receiving of powders of iron group. To the powder of oxygen-containing composition of metal of iron group it is added 2-30 wt % of nitrate of corresponding metal, it is implemented grinding in liquid, virtually not dissolving basic compound, but dissolving nitrate, and it is reduced received mixture by hydrogen.
EFFECT: it is provided receiving of powder with grain size less than 2,0 mcm, allowing ignition.
