The present lecture is intended to introduce the research works done by the various investigators, concerning on the production of aluminium by means of thermal reduction with carbon.After brief introduction, the possibitily of the reduction of alumina with carbon has been treated theoretically and the energy consumption for the production of crude aluminium has also been illustrated.In the third section, so-called carbide process invented by E. Grünert has been introduced and the semiindustrial furnaces for the production or for the decomposition of aluminium carbide, which are proposed by the Pechiney-Ugine group, has been described.In the fourth section, various methods of extraction of aluminium from thermally reduced crude aluminium alloy, ie. method of distillation, method of separation of the liquid phase centrifugally, method of extraction of aluminium using zinc, magnesium, mercury and lead as the solvent, method of extraction of aluminium as aluminium subchloride and method of electrolysis, have been introduced.

Molten aluminium is equilibrated with pure carbon over a temperature range of 800° to 1400°C under the pressure of 4×10-5mm Hg, and atmosphere. of argon Solubility of carbon in liquid aluminium under pres sure of 4×10-5mmHg is 0.10, 0.14, 0.16, and 0.32wt% at 800°, 1000°, 1100°, and 1200° respectively, and is high compared with the value obtained in the atmosphere of argon. The difference of solubility data was discussed as based on the existence of small amount of oxygen in the system. Solibility of carbon in solid aluminium is estimated to be 0.015wt% from the analytical data of graphite carbon.
