A mass of solid aluminium carbide containing product is produced by a process in which a mixture is formed of an aluminium containing material and a carbonaceous material consisting of, containing or yielding carbon. Then the resulting mixture is heated to a temperature sufficient to react carbon of the carbonaceous material with the aluminium of the aluminium containing material to produce solid aluminium carbide. The solid aluminium carbide then is able to be heated with an aluminium compound selected from AI 2 O 3 , AI 4 CO 4 , AIO, AI 2 O and mixtures thereof, to produce aluminium metal and carbon monoxide. |
