ABSTRACT:
The invention relates to a method for producing metal powders, where the employed raw materials are metal ions in a liquid phase. According to the invention, at a preliminary stage of the method the liquid phase containing metal ions is reduced with hydrogen at an increased pressure and raised temperature in order to produce porous, sponge-like metal powder. The obtained porous, sponge-like metal powder is further processed at a high temperature, for instance by means of plasma, in order to improve the qualities of the metal powder.
