Thermal Properties of Japanese Colloidal Earth as the Source Material of Direct Reduction (Studies on the Production of Crude Aluminium Alloy by the Direct Reduction of Aluminous Ores)

The carbothermic reduction of Al2O3 and mixtures of Al2O3 with Fe2O3, NiO, Cu and SiO2 was studied in argon and CO atmosphere, respectively. Furthermore, the reduction of bauxite and colloidal earth available for the direct reduction of aluminum was also examined. observed. Prior to the formation of Al-Si alloys, the reaction of the Al2O3-SiO2-C system in argon showed a simultaneous change of Al2O3-C and SiO2-C systems.

As a part of the study relating to direct reduction of aluminum, the preparation of aluminum alloy was carried out by means of the 10kVA Girod and the 70kVA Heroult furnace using bauxite and colloidal earth, and the reduction process and operational conditions were clarified.During the preliminary treatment of the source materials, it became clear that briquetting and pelletizing were more effective to make the reduction easier and to obtain a more uniform tapped alloy than in the case of the separate charge of bauxite and colloidal earth. In addition, a larger amount of the alloy with a higher aluminum content in the tapped metal was obtained from the mixture.The differences in the carbonaceous materials among charcoal, coal and cokes were not made clear.The alloy containedFe2O3 was about twice greater than them. Chemical and X-ray analysis of the residual matter showed that the alloy was formed mainly between aluminum oxide and silicon carbide.
