Abstract

As the studies of various treating conditions of methanolic bromine solution and of the behaviors of various component inclusions in it in comparison with methanolic iodine solution have led to successful results, as described in the previous reports, in this last study the residues of twenty specimens of iron and steel in the shape of drillings or solid pieces were determined as oxides of silicon, aluminum, manganese, and iron, after treatment with the both solutions at ordinary temperature as well as at 60°C, respectively. From the above experiments, it was concluded that separation with 10% methanolic bromine solution at ordinary temperature is more suitable than iodine methods for separation of oxide inclusions in plain carbon steel containing less than 0.5%C, is more rapid and specific, and less expensive than any hitherto developed separation methods.
