Aus diesen Versuchen ist erkennbar, dass schon geringe Nickelanteile den Pressdruck, aber auch die Presstemperatur und gegebenenfalls Pressdruck und-temperatur herabzusetzen vermögen. Die beobachtete günstige Wirkung des Nickels tritt, wie Untersuchungen ergeben haben, im gesamten angegebenen Bereich der   Cer- (Mischmetall-) Bisenlegierungen,   also auch bei höheren und andern Mischmetall-Eisengehalten als in der obigen Aufstellung angegeben, ein. 



   Statt Nickel kann man erfindungsgemäss als Äquivalent des Nickels auch Kobalt als die Presseigenschaften verbessernden Zusatz verwenden, jedoch ist Kobalt viel teurer als Nickel, ohne gegenüber diesem einen besonderen Vorteil zu bieten. Legierungen des Cers (Mischmetalls) mit Eisen, Kobalt und Nickel, einzeln oder zusammen, sind in der deutschen Patentschrift Nr. 154807 genannt worden ; die günstige Wirkung eines Nickelzusatzes beim Strangpressen von   Cer- (Mischmetall-) Eisenlegierungen   ist jedoch bisher nicht beschrieben worden. 



    PATENTANSPRÜCHE :    
1. Verwendung von   Cer- (Mischmetall-) Eisenlegierungen   mit   4 - 400/0   Eisen,   0,1- 201lu   Nickel und gegebenenfalls   bis 8% ändern bei   pyrophoren Cer-Eisenlegierungen bekannten Zusätzen, wie z. B. Mg, Al, Sn, Cu, Rest Cer bzw. Mischmetall, zur Herstellung von Zündsteinen nach dem Strangpressverfahren.

   1 = not compressible
From these tests it can be seen that even small amounts of nickel can reduce the pressing pressure, but also the pressing temperature and possibly the pressing pressure and temperature. As studies have shown, the observed beneficial effect of nickel occurs in the entire specified range of cerium (mischmetal) bis-iron alloys, i.e. also with higher and different mischmetal iron contents than specified in the list above.



   Instead of nickel, according to the invention, cobalt can also be used as the equivalent of nickel as an additive which improves the press properties, but cobalt is much more expensive than nickel without offering any particular advantage over it. Alloys of cerium (mischmetal) with iron, cobalt and nickel, individually or together, have been mentioned in German patent specification No. 154807; however, the beneficial effect of adding nickel in the extrusion of cerium (mischmetal) iron alloys has not yet been described.



    PATENT CLAIMS:
1. Use of cerium (mixed metal) iron alloys with 4 - 400/0 iron, 0.1- 201lu nickel and possibly up to 8% change in pyrophoric cerium iron alloys known additives such as z. B. Mg, Al, Sn, Cu, remainder cerium or mischmetal, for the production of flints by the extrusion process.
