Description
Behandlung von Aluminiumsulfidschmelzen Bisher hat man die durch Reduktion in Gegenwart von schwefelhaltigen Stoffen gewonnene Schmelze, bestehend aus Aluminiumoxyd und Aluminiumsulfid, die in folgendem kurz als Sulfidschmelze bezeichnet werden soll, nach dem Erstarren mit Wasser aufgeschlossen.Treatment of aluminum sulphide melts So far, one has that by reduction Melt obtained in the presence of sulphurous substances, consisting of aluminum oxide and aluminum sulfide, hereinafter referred to as sulfide melt for short should be digested with water after solidification.
Es ist bekannt, Aluminiumoxydschmelzen mit Gasen oder Flüssigkeiten, insbesondere Wasser, schnell abzukühlen, um eine besonders für die Elektrolyse geeignete Tonerde von großer Feinheit zu erzielen.It is known to melt aluminum oxide with gases or liquids, especially water, to be cooled quickly to make a particularly suitable one for electrolysis To obtain clay of great fineness.
Erfindungsgemäß wird dieses Verfahren zur Behandlung der nach dem Patent 451 523 hergestellten Sulfidschmelzen benutzt. Es hat sich gezeigt, daß das bekannte Verfahren hier mit viel größerer Intensität vor sich geht als bei den angegebenen bekannten Verfahren. Der Aluminiumsulfidgehalt reagiert mit dem Wasser, und es entwickeln sich derartige Energien, daß das Material, man kann beinahe sagen, bis zur molekularen Feinheit zerfällt. Man erhält eine Tonerde, wie sie sonst aus Aluminaten nur durch Ausrühren hergestellt werden konnte. Zur Abschreckung können verschiedene Wege beschritten werden, z. B. kann man die Schmelze direkt in Wasser laufen lassen, für dessen Erneuerung man natürlich Sorge tragen muß.According to the invention this method is used for treating the sulfide melts prepared according to the patent 451,523. It has been shown that the known method proceeds here with much greater intensity than in the case of the known methods indicated. The aluminum sulphide content reacts with the water, and such energies develop that the material, one could almost say, disintegrates to the point of molecular fineness. The result is an alumina that could otherwise only be produced from aluminates by stirring. Various ways can be used as a deterrent, e.g. B. you can let the melt run directly in water, for the renewal of course you have to take care.
Während sonst die Tonerde aus der Sulfidschmelze, wenn man sie auf einem io ooo-Maschensieb behandelt, etwa 7011/o Rückstand auf diesem Sieb beläßt, bleiben von der Tonerde der abgeschreckten Schmelze nur noch etwa 1711111 auf dem Sieb zurück. Eine Bayer-Tonerde, die auch auf dem io ooo-Maschensieb behandelt wurde, hinterließ im Durchschnitt 12111o Rückstand. Man kommt also mit Hilfe des Abschreckens tatsächlich auf Korngrößen der Tonerde, die denen der Bayer-Tonerde ungefähr gleichkommen.While otherwise the alumina from the sulphide melt when you put it on treated with a 10,000 mesh sieve, leaving about 7011 / o residue on this sieve, Only about 1711111 of the alumina of the quenched melt remain on the Sieve back. A Bayer clay that was also treated on the io ooo mesh sieve, left an average of 12,110 residue. So you come with the help of deterrence actually on grain sizes of the alumina which are approximately equal to those of Bayer alumina.
