ACD Anode-cathode-distance (ACD) is the anode-to-molten aluminium spacing. |
|
Anode 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. |
|
Bauxite Is the most common ore of aluminium. |
|
Bayer Process 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'. |
|
Busbar The external aluminium bar used to lead current between pots to the electrod contacts. |
|
Cathode lining The carbonaceous negative electrode that is also used for containing the metal and the electrolyte. |
|
Conductors Materials that are made up of atoms whose electrons are easily freed. |
|
Crust The solidified electrolyte-alumina power that forms on top of the pot. |
|
Current effeciency 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. |
