PURPOSE: A method for producing metal powder capable of controlling shape and grain size is provided to control a supply flux of N2H4(Hydrazine) by 0.6 to 10 ml/min, thereby manufacturing a good quality metallic powder having a spherical shape and a uniform particle size distribution. CONSTITUTION: A method for producing metal powder capable of controlling shape and grain size is as follows. A seed suspension having seed particles is prepared. A metal oxide is added to the seed suspension so that metal oxide slurry is formed. N2H4 is supplied to the metal oxide slurry and a metal oxide included in the metal oxide slurry is restored so that the metallic powder grows in the seed particles. The N2H4 is supplied at a flow rate of 0.6 to 10 ml/min. |
