Description
Verfahren zur Herstellung von Legierungen der Erdalkalimetalle. Zusatz zum Patent 38i049. Eine weitere Ausführungsform des im Patent 381o49 beschriebenen Verfahrens besteht darin, ein Mehrfaches der theoretischen Menge des zur Durchführung der Reaktion erforderlichen Halogensalzes zu verwenden. Bei Anwendung eines solchen erheblichen Überschusses an Halogensalz im Verhältnis zu der Menge des in der Metallegierung enthaltenen Alkalimetalls ist es möglich, eine hinreichende Reaktionsfähigkeit -der Salzschmelze bis zum vollständigen Übergang des Natriums in die Salzschmelze aufrechtzuerhalten. Die Menge der sich durch den Übergang ödes Alkalimetalls in die Salzschmelze bildenden schwer schmelzbaren Oxychloride bleibt in .diesem Falle im Verhältnis zu der Gesamtmenge des verwendeten Halogensalzes so gering, @daß der ungünstige Einfluß, den diese Oxychloriide auf den Flüssigkeitsgrad des Halogensalzes ausüben, unterdrückt wird. Man wird in der Regel mit etwa dann zweifachen bis fünffachen der theoretisch errechneten Halogensalamenge auskommen, um die Reaktion in einer praktisch genügend kurzen Zeit durchzuführen. Bei der Herstellung einer BleiJKalzium Legierung mit 2 Prozent Kalzium durch Eimvirkenla,-ssen von Kalziumchlorid auf Zoo kg einer Blei-Natrium-Legierung, welche 2,3 kg Natrium enthält, wird man beispielsweise 15 kg Kalziumchlorid verwenden, wähnend die theoretisch zur Umsetzung erforderliche Menge nur 5,6 kg beträgt.Process for the production of alloys of the alkaline earth metals. additive for patent 38i049. Another embodiment of that described in the '381o49 patent Procedure consists in a multiple of the theoretical amount of the to carry out to use the halogen salt required for the reaction. When using such significant excess of halogen salt relative to the amount of that in the metal alloy contained alkali metal, it is possible to have a sufficient reactivity -the Maintain molten salt until the sodium has completely migrated into the molten salt. The amount of metal formed by the transition of the dull alkali metal into the molten salt In this case, the difficult-to-melt oxychloride remains in proportion to the total amount of the halogen salt used so little that the unfavorable influence that this Oxychloride exert on the degree of fluidity of the halogen salt is suppressed. As a rule, you will get around twice to five times the theoretically calculated value Halogen salam sufficient to get the reaction in a practically short enough time perform. When producing a lead-calcium alloy with 2 percent calcium by Eimvirkenla, -essen of calcium chloride on Zoo kg of a lead-sodium alloy, which contains 2.3 kg of sodium, you will use, for example, 15 kg of calcium chloride, while the amount theoretically required for implementation is only 5.6 kg.
