Abstract

A process for producing metallic powders a chlorination step for continuously producing chloride gas of metal by reacting metal with chlorine gas, and a reduction step for continuously reducing the metallic chloride gas by reacting the metallic chloride gas produced in the chlorination step with reducing gas. Regulating the feed rate of the chlorine gas can control the feed rate of the metallic chloride gas, whereby the particle diameters of produced metal powders can be stably controlled. Thus, the invention can make the particle diameters stable and arbitrarily control the diameters in the range of 0.1 to 1.0 .mu.m.
