Extraction of Aluminium : Why carbon anodes?
Hi
In the extraction of Aluminium from Bauxite Al2O3, using electrolysis, why are carbon anodes used? Is there no alternative?
Because the oxygen produced at the carbon anode degrades the anode, producing CO2, meaning that they need periodic replacement. Is carbon used simply because it works out cheaper/more economical than any potential alternatives? Or are there no alternatives?
Cheers guys

The process is carried out at about 950 degrees. There are few materials that would be able to withstand the temperature and not get affected...

Aha, of course! I see now! Thanks, much appreciated!
