Extraction of Aluminum by AlCl Disproportionation Process in Vacuum
The extraction of aluminum by the AlCl disproportionation process in vacuum was researched using the furnace designed by ourselves.The features of aluminum products were characterized by X-ray diffraction,scanning electronic microscope and energy-dispersive X-ray spectroscopy.The results indicated that the purity of aluminum products increased with decreasing condensation temperature; aluminum products could be oxidized as their size was too small; the residues of the extraction of aluminum from alumina could be further treated with this process to generate metallic aluminum with a little carbon; aluminum products with high Al4C3,C and Al2O3 impurities could be purified by this process.The conclusions could provide bases for the industrial application of the process.
