A method for producing a metal powder, comprising an electric explosion of a piece of a steel wire carried out inside a reactor at a pressure of a gaseous medium of 105 Pa and its forced circulation, characterized in that the method further comprises a pre-evacuation of a volume contained inside the reactor and pipes connecting it to a cyclone, whose lower part is equipped with a hopper, to a residual pressure of 10−2 Pa, then it is filled with carbon monoxide to a pressure of 105 Pa at a gas flow rate of 10 m/s at a reactor inlet, the electric explosion of the steel wire made of low-carbon steel is then carried out at a specific energy of 7-18 kj/g and a pulse duration of 1.2-2 μs, products of the electric explosion are extracted by gas flow through the cyclone into the hopper to deposit, once the hopper is filled, the process is halted, the hopper is disconnected from the cyclone, closed with a lid with an opening, and kept in this state for at least 48 hours, the resulting powder is then removed and placed into a container for storage.
