år för att rena aluminium – men liksom de andra idéerna för att framställa stål  I samband med elektrifieringen av ett hållbart samhälle kan SOC (Solid Oxide Cell)-, och särskilt Solid Oxide Electrolysis Cell (SOEC)  The diagram shows an aluminium oxide electrolysis cell. Both the negative electrode (cathode) and positive electrode (anode) are made of graphite, which is a form of carbon. Aluminium ions receive Electrolysis is used to extract Aluminium from Aluminium Oxide ( Al2O3 ). To do this, the Al2O3 must be molten however, the melting point of Al2O3 is over 2000° C which is very expensive and inefficient to heat the Al2O3 up that much. To combat this and make the extraction of aluminum cheaper, cryolite is added.
