A high yield of aluminum alloys was difficult to achieve with a blast furnace, because both heating samples and reducing samples were done in the same chamber. In this report, we achieved a high yield of Al-Fe alloys, 70wt%, by carbothermic reduction of Al2O3-Fe2O3-C samples using a new indirect heating method. The method for preparing the sample to be reduced was based on the reduction mechanism of alumina. The sample was prepared by mixing graphite powders (0.3-0.5mm) coated with fine α-Fe2O3 powders (1μm) and α-Al2O3 powders (20-80μm) and subsequent compaction.
