Electrolysis of aluminium oxide - cryolite
To electrolyse the aluminium oxide we must first melt it. This enables the ions to move to the electrodes.
Unfortunately aluminium oxide has a very high melting point. It melts at 2050ºc. Howver, chemists have found a way of saving at least some energy. This is done by mixing the aluminium oxide with molten…
