    Aus diesen Verbindungen, z. B. Stickstoff-Thotiujm lassen sich leicht Stäbchen und dergleichen formen, die dann unter Luttabschluss geglüht werden, was z. B. durch den elektrischen Strom geschehen kann. Hierbei gibt das Stickstoff-Thorium vollständig seinen Stickstoff ab, so dass ein Körper aus metallischem Thorium, eventuell mit den durch etwaige Zusätze bedingten Beimengungen erhalten wird von derselben Gestalt, die der Stickstoff-Thorium Körper hatte. 



  Die Erhitzung des Fadens behufs Austreibung des Stickstoffes kann natürlich auch hier in der bekannten Weise durch Hindurchleiten eines elektrischen Stromes unter Luftabschluss (d. h. im Vacuum, in indifferenten Gasen oder in Kohle) erfolgen. Wofern die Leitungsfähigkeit der gewählten Ausgangsmaterialien nicht genügend erscheint, um diese elektrische Erhitzung praktisch durchzuführen, kann dieselbe durch einen angemessenen Zusatz bereits reducierten Metalles oder eines entsprechenden Carbides zu den Verbindungen wesentlich verbessert werden, Die Egalisierung und Widerstandsregulierung des Fadens, falls eine solche sich als wünschenswert erweist, kann durch ein Präparierverfahren, ähnlich dem bei Kohlefäden bekannten, erfolgen, durch welches die Fäden mit einem festhaftenden Überzug des gleichen oder eines anderen Metalles versehen werden.

   Selbstverständlich kann man zur Herstellung von Glilhkörpufn nicht allein die Verbindung eines einzelnen Metalles verwenden, sondern auch Mischungen mehrerer derselben, so dass man als Endproduct eine Legierung der betreffenden Metalle bekommt. In derselben Weise kann man auch Legierungen von Thorium, Zirkonium Yttrium u. s. w. mit Metallen der Ccritgruppe herstellen und z. B. Glühkörper gewinnen, welche aus Thorium mit einem bestimmten Gehalt von Cermetall bestehen.

    From these compounds, e.g. B. Nitrogen Thotiujm can easily be shaped rods and the like, which are then annealed under lutt, what z. B. can be done by the electric current. Here, the nitrogen thorium completely releases its nitrogen, so that a body made of metallic thorium, possibly with the admixtures caused by any additives, is obtained of the same shape as the nitrogen thorium body.



  The heating of the thread in order to expel the nitrogen can of course also take place here in the known manner by passing an electric current through it in the absence of air (i.e. in a vacuum, in inert gases or in carbon). If the conductivity of the selected starting materials does not appear to be sufficient to carry out this electrical heating in practice, the same can be significantly improved by an appropriate addition of already reduced metal or a corresponding carbide to the connections, the leveling and resistance regulation of the thread, if such is desirable proves, can be done by a preparation process similar to that known for carbon threads, by which the threads are provided with a firmly adhering coating of the same or a different metal.

   Of course, one can not only use the compound of a single metal for the production of incandescent bodies, but also mixtures of several of the same, so that an alloy of the metals in question is obtained as the end product. In the same way, alloys of thorium, zirconium, yttrium and the like can also be used. s. w. produce with metals of the Ccritgruppe and z. B. win incandescent bodies, which consist of thorium with a certain content of cermetall.
