Verfahren zur Herstellung von Fäden für elektrische E ! Shtampen aus schwer schmelzenden Metallen.
Fäden für elektrische Glühlampen aus schwer schmelzenden Metallen, wie Niob, Tantal, Molybdän, Wolfram, Uran, Titan, Thorium, Zirkon, sind bereits in der Weise hergestellt worden, dass man die Oxyde dieser Metalle mit einem kohlenstoffreien Binde- mitte.)/. zu einer plastischen Masse geformt und dann die aus dieser Masse hergestellten Fäden einem Reduktionsprozess unterworfen hat. Auch wurde bereits vorgeschlagen, die reinen Metalle mit kohlenstoffreien Bindemitteln, wie z. B. Schwefel, zu Fäden zu verarbeiten ;

wird das pulverförmige Metall mit einer Lösung von Schwefel-Ammonium zu einer plastischen Masse zusammengerührt: aus dieser Masse werden alsdann die Fäden in bekannter Weise hergestellt.
Dieselben sind ohne weiteres stromleitend ; bei der Stromeinleitung verdampft das Schwefel-Ammonium. Die sich unter Umständen nur in ganz geringer

Process for making threads for electrical E! Shtamps made from refractory metals.
Threads for electric incandescent lamps made of difficult-to-melt metals, such as niobium, tantalum, molybdenum, tungsten, uranium, titanium, thorium, zircon, have already been manufactured in such a way that the oxides of these metals are bonded with a carbon-free binder.) /. formed into a plastic mass and then subjected the threads made from this mass to a reduction process. It has also already been proposed that the pure metals with carbon-free binders, such as. B. sulfur, to be processed into threads;
EMI1.1
If the powdered metal is mixed with a solution of sulfur-ammonium to a plastic mass: from this mass the threads are then made in the known manner.
They are readily conductive; When the current is introduced, the sulfur-ammonium evaporates. Which may only be very low
