Description
Verfahren und Vorrichtung zum elektrolytischen Herstellen von hochreinem Gallium Zusatz zum Patent: 1141461 Gegenstand des Hauptpatentes ist ein Verfahren und eine Vorrichtung zum Herstellen von hochreinem Gallium durch elektrolytische Abscheidung, wobei als Elektrolyt eine Lösung eines Galliumkomplexes vom Typ Ga [GaX4] in einem nichtwäßrigen organischen Lösungsmittel verwendet wird und wobei X ein Halogenelement bedeutet.Method and device for the electrolytic production of high purity Gallium Addition to the patent: 1141461 The main patent relates to a process and an apparatus for producing high purity gallium by electrolytic Deposition, with a solution of a gallium complex of the Ga type as the electrolyte [GaX4] is used in a non-aqueous organic solvent and wherein X represents a halogen element.
Das Verfahren nach dem Hauptpatent basiert auf der Erkenntnis, daß die Galliumkomplexe vom genannten Typ in nichtwäßrigen organischen Lösungsmitteln, z. B. Benzol, Toluol oder Xylol, eine gute Löslichkeit und elektrische Leitfähigkeit aufweisen und daß aus solchen Lösungen als Elektrolyt Gallium abgeschieden werden kann. Dies war um so weniger zu erwarten, als die genannten Komplexe salzartig aufgebaut sind.The method according to the main patent is based on the knowledge that the gallium complexes of the type mentioned in non-aqueous organic solvents, z. B. benzene, toluene or xylene, good solubility and electrical conductivity have and that gallium is deposited as an electrolyte from such solutions can. This was all the less to be expected as the complexes mentioned were built up like salt are.
Es wurde nun gefunden, daß man das Verfahren zum Herstellen von hochreinem Gallium durch elektrolytische Abscheidung, wobei nach Patent 1141461 als Elektrolyt eine Lösung eines Galliumkomplexes vom Typ Ga [GaX4] - X bedeutet ein Halogenelement - in einem nichtwäßrigen organischen Lösungsmittel verwendet wird, dahin abwandeln kann, daß in dem Komplextyp Aluminium an Stelle des komplexgebundenen Galliums tritt. Die Löslichkeit des erfindungsgemäß zu verwendenden Komplexes Ga [AIX4] beträgt z. B. für X = Br in Benzol bei 20° C etwa 1200 g/1. Die spezifische elektrische Leitfähigkeit x (in 52-1 cm-') des erfindungsgemäßen Elektrolyten liefert bei einer Konzentration von 60 Gewichtsprozent Ga [A1Br4] und einer Temperatur von 22 bzw. 40° C die Werte 0,015 bzw. 0,02.It has now been found that the method for producing high purity gallium by electrolytic deposition, wherein, after Patent 1 141461 as electrolyte a solution of a gallium-type Ga [GaX4] - X represents a halogen element - is used in a non-aqueous organic solvent, then can modify that in the complex type aluminum takes the place of the complex-bound gallium. The solubility of the complex Ga [AIX4] to be used according to the invention is z. B. for X = Br in benzene at 20 ° C about 1200 g / l. The specific electrical conductivity x (in 52-1 cm- ') of the electrolyte according to the invention at a concentration of 60 percent by weight Ga [A1Br4] and a temperature of 22 and 40 ° C. gives the values 0.015 and 0.02, respectively.
Ein großer Vorteil gegenüber den bisher bekannten Verfahren liegt in den geringen Herstellungskosten des Elektrolyten.There is a great advantage over the previously known methods in the low manufacturing cost of the electrolyte.
Die Darstellung erfolgt nach folgenden Reaktionsgleichungen: 4 Ga -I- 6 X2---> 4 GaX3; 4 GaX3 -I- 3 AI-> 3 Ga [A1X4] -I- Ga. Der Komplex wird mit einem nichtwäßrigen organischen Lösungsmittel, z. B. mit Benzol, Toluol oder Xylol, in einem Extraktor, z. B. in einer Soxhlet-Apparatur, extrahiert und so der erfindungsgemäße Elektrolyt gewonnen.The representation is based on the following reaction equations: 4 Ga -I- 6 X2 ---> 4 GaX3; 4 GaX3 -I- 3 AI-> 3 Ga [A1X4] -I- Ga. The complex is with a non-aqueous organic solvent, e.g. B. with benzene, toluene or xylene, in an extractor, e.g. B. in a Soxhlet apparatus, extracted and so the invention Electrolyte obtained.
