  • Method for producing metal powders
    Patent number: 5176810
    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.
    Type: Grant

  • Method for producing metal powders from liquid phase containing metal ions
    Patent number: 5135567
    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.
