Patentiert im Deutschen Reiche vom 12. September 1905 ab.Patented in the German Empire on September 12, 1905.
Vorliegende Erfindung hat ein Verfahren zum Gegenstande, um aus Wolfram- oder Molybdänoxyden unter eventuellem Zusatz derselben Metalle oder anderer kohlenstofffreier Wolfram- und Molybdänverbindungen und ohne Zuhilfenahme organischer Bindemittel, Fäden für elektrische Glühlampen herstellen zu können.The present invention has a method as an object to produce from tungsten or Molybdenum oxides with possible addition of the same metals or other carbon-free ones Tungsten and molybdenum compounds and without the aid of organic binders, To be able to produce threads for electric light bulbs.
Wenn man die Trioxyde des Wolframs oderIf one considers the trioxides of tungsten or
ίο Molybdäns längere Zeit mit AmmoniakfLüssigkeit reibt, so entsteht eine kompakte zähe Masse. Es liegt dann jedenfalls eine komplizierte Verbindung vor, in der normale Para- und auch Metasalze des Wolframs oder Molybdäns vertreten sind. Diese Masse läßt sich vortrefflich durch Düsen zu Fäden pressen, welche rasch an der Luft erstarren. Solche Fäden sind nicht stromleitend. Werden sie aber unter Luftabschluß geglüht, so verlieren sie die ursprüngliche lichte Farbe, dies deshalb, weil dabei die Ammoniumverbindungen zerstört werden. Der Faden besteht nun aus Metall oder niederen Oxyden. Sein Leitungswiderstand hat beträchtlich abgenommen. Man kann solche Fäden unter Luftabschluß mittels des elektrischen Stromes leicht zum Glühen bringen, wobei auch die Sinterung und die eventuelle Elektrolyse vor sich geht.ίο Molybdenum with ammonia liquid for a long time rubs, this creates a compact, viscous mass. In any case, there is a complicated one Compound before, in the normal para and also metasalts of tungsten or molybdenum are represented. This mass can be excellently pressed into threads through nozzles, which freeze quickly in the air. Such threads are not conductive. But they will annealed in the absence of air, they lose their original light color, this is why, because this destroys the ammonium compounds. The thread now consists of metal or lower oxides. Its line resistance has decreased considerably. Such threads can easily be made to glow in the absence of air by means of the electric current bring, with sintering and eventual electrolysis also going on.
