Abstract (en)
[origin: ES8203989A1] A solid cathode in a fused salt electrolytic cell for the production of aluminum is made up of individually exchangeable elements (10). These cathode elements are made up of two parts which are rigidly joined together and which are resistant to thermal shock. The upper part (12) which projects from the molten electrolyte (30) into the precipitated aluminum (26), or the coating on this part (12), is made of a material which, at working temperature, is a good electrical conductor, is chemically resistant and is wet by aluminum. The lower part (14,16), which is exclusively in the liquid aluminum (26), or the coating on this part (14,16) is on the other hand made of an insulating material which can withstand molten aluminum.

Eine Festkörperkathode in einer Schmelzflusselektrolysezelle zur Herstellung von Aluminium besteht aus einzeln auswechselbaren Elementen (10). Zwei gegen Wärmeschocks widerstandsfähige, starr miteinander verbundene Teile bilden diese Kathodenelemente. Der obere, vom schmelzflüssigen Elektrolyten (30) in das abgeschiedene Aluminium (26) hineinragende Teil (12) bzw. dessen Beschichtung besteht aus einem bei Arbeitstemperatur elektrische gut leitenden, chemisch beständigen und von Aluminium benetzbaren Material. Der untere, ausschliesslich im flüssigen Aluminium (26) angeordnete Teil (14, 16) bzw. dessen Beschichtung dagegen besteht aus gegen Aluminium beständigem Isolatormaterial.
