Anode-cathode-distance (ACD) is the anode-to-molten aluminium spacing.
The carbon mass connected to the more positive side of the power supply and used for the electrochemical removal of oxide ions, in the process itself being consumed.
Is the most common ore of aluminium.
A German Karl Joseph Bayer invented a process in the year 1888 to refine Bauxite and recover nearly pure alumina. The process is named 'Bayer Process'.
The external aluminium bar used to lead current between pots to the electrod contacts.
The carbonaceous negative electrode that is also used for containing the metal and the electrolyte.
Materials that are made up of atoms whose electrons are easily freed.
The solidified electrolyte-alumina power that forms on top of the pot.
The ratio of the quantity of metal produced in the pot by passing of current compared to that of the theoretical amount expected from Faraday's Law. Expressed as a percentage.
Electrolyte or bath
Motlen Cryolite (Na3ALF6) is the major component (80 - 85%) of the electrolyte or bath.
