Abstract
The invention relates to a method for producing metal powders from reactive metals, when the employed raw materials are metal ions in a liquid phase. According to the invention, the metal ions are first reduced into metal in a molten salt electrolysis. The obtained reduction products are further subjected to a high-temperature treatment, for example by means of plasma, in order to improve the powder qualities of the metal. The metal to be treated is for instance titanium or zirconium.
