PURPOSE: To obtain a metal powder reduced in oxidation, by a method wherein a molten metal is comminuted by using inert gas as a spray medium and the comminuted metal is cooled in a liquid cooling medium such as an org. solvent, mineral oil or animal and vegetable oil.
CONSTITUTION: The molten metal 2 in a tandish 1 is flowed down into a protective curtain 5 from the effluent nozzle provided to the bottom part of the tandish 1 while inert gas, for example, Ar, He or N2 is injected to the flowed-down molten metal from a plurality of inert gas nozzles 7 provided to an inert gas supply pipe 6 to comminute the same into metal particles 10 which are, in turn, fallen into the liquid cooling medium 11 in a cooling tank 12 to be cooled and solidified. As the liquid cooling medium, an org. solvent, mineral oil or animal and vegetable oil are used. The solidified metal particles 13 are taken out by a conveyor 14.
