OSTI ID:5334374
Production of aluminum and magnesium by electrolysis of molten salts is studied with Raman spectroscopy. The I.G. process and aluminum chloride alkali chloride process were selected for the study. By measuring Raman spectra for the pure molten MgCl/sub 2/ it was confirmed that the experimental set-up is correct. Magnesium and aluminum were confirmed to exist in their electrolyte melts as tetrahedrally coordinated species. Raman spectra for MgCl/sub 2/ and AlCl/sub 3/ during electrolysis showed that it can be used as a reference for concentration change. Some result for the AlCl/sub 3/ electrolysis gave a clue to the problem of the occurrence of new species.
