More Information
Summary:The invention relates to a method for producing metal and alloy powders containing at least one of the metals iron, copper, tin, cobalt or nickel. According to the method an aqueous solutions of metal salts is mixed with an aqueous carboxylic acid solution, the precipitation product is separated from the mother liquor and the precipitation product is reduced to metal. Es wird ein Verfahren zur Herstellung von Metall- und Legierungspulvern, enthaltend mindestens eines der Metalle Eisen, Kupfer, Zinn, Kobalt oder Nickel durch Vermischen von wäßrigen Metallsalzlösungen mit einer wäßrigen Carbonsäurelösung, Abtrennen des Fällungsproduktes von der Mutterlauge und Reduktion des Fällungsproduktes zum Metall, beschrieben.
