A
ACDAnode-cathode-distance (ACD) is the anode-to-molten aluminium spacing. |
AnodeThe 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. |
B
BauxiteIs the most common ore of aluminium. |
Bayer ProcessA 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'. |
BusbarThe external aluminium bar used to lead current between pots to the electrod contacts. |
C
Cathode liningThe carbonaceous negative electrode that is also used for containing the metal and the electrolyte. |
ConductorsMaterials that are made up of atoms whose electrons are easily freed. |
CrustThe solidified electrolyte-alumina power that forms on top of the pot. |
Current effeciencyThe 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. |
E
Electrolyte or bathMotlen Cryolite (Na3ALF6) is the major component (80 - 85%) of the electrolyte or bath. |
