FIELD: metallurgy.
SUBSTANCE: procedure for production of metal powder of molybdenum consists in reduction of molybdenum oxide (MoO3) with metal-reducer in melt of sodium chloride of potassium chloride or their mixture at ratio 1:1 at temperature 770-850°C. Upon reduction metal phase of molybdenum powder is separated from reaction mass. Reduction is performed with aluminium powder at ratio of source molybdenum oxide (MoO3) to melt equal to 1:3-5.
EFFECT: reduced temperature of melting at sufficiently complete extraction of molybdenum from oxide in form of metal high dispersed powder of molybdenum and reduced consumption of reagents.
