Description
Verfahren zur Herstellung von Zirkonmetall. Zur Reduktion der Zirkonerze zu Metall ist eine sehr hohe Temperatur erforderlich. Am besten ist diese Reduktion im elektrischen Ofen zu erreichen. Die Ausbeute an erhaltenem Zirkonmetall ist jedoch gering, weil durch das sich entwickelnde Kohlenoxyd ein großer Prozentsatz Zirkon in Nebelform mitgerissen und wieder zu Oxyd verbrannt wird. Diese Übelstände können behoben werden, wenn man den Prozeß unter erhöhtem Druck durchführt.Process for the production of zirconium metal. For the reduction of zirconium ores to metal a very high temperature is required. This reduction is best in the electric oven. However, the yield of zirconium metal obtained is low, because a large percentage of zirconium is produced by the carbon dioxide that is formed is carried away in the form of a mist and burned back to oxide. These evils can can be corrected if the process is carried out under increased pressure.
Im folgenden soll an Hand eines Ausführungsbeispiels der Vorgang erläutert werden. In ein druckfestes Gefäß, in das zwei isolierte Kohlenelektroden hineingeführt sind, wird Zirkonerz oder -oxyd mit Kohle im stöchiometrischen Verhältnis und gut vermischt hineingegeben. Die Reaktion kann z. B. eingeleitet werden dadurch, daß man das zu behandelnde Gut in glühendem Zustand in das Gefäß kippt, wodurch die Masse selbst für den elektrischen Strom leitend wird, oder indem man, ähnlich wie nach dem Karbortindumverfahren, mittels einer leitenden Kohlenseele die Erhitzung des Reaktionsgutes vornimmt. Den erhöhten Druck erreicht man bei Verschluß des Gefäßes durch das sich entwickelnde Kohlenoxydgas.The process is explained below using an exemplary embodiment will. In a pressure-resistant vessel, into which two insulated carbon electrodes are inserted Zirconium ore or oxide becomes stoichiometric with coal and is good mixed in. The reaction can e.g. B. be initiated by the fact that you tip the goods to be treated in the glowing state in the vessel, whereby the Ground itself becomes conductive for the electric current, or by one, similar to according to the carbortindum process, heating by means of a conductive carbon core of the reaction product. The increased pressure is achieved when the vessel is closed by the developing carbon dioxide gas.
