It is based on a process known as electrolysis, in which an electrical current is used to produce the constituent elements from a chemical compound. In this case, aluminum oxide is separated into ...

This mixture melts at a lower temperature than aluminium oxide, reducing costs. Cryolite also increases conductivity. The diagram shows an electrolysis cell used to extract aluminium. Both ...

Electrolysis can be used to extract the ... aluminium ions gain electrons from the cathode, and form molten aluminium oxide ions lose electrons at the anode, and form oxygen molecules The oxygen ...

Aluminum has a natural oxide layer that forms immediately after ... Galvanic corrosion is often referred to as “electrolysis”, but this is not quite accurate, as they are related but not ...
