  • Magnesium Industry | Fluorinated Gas Partnership Programs

    Emission SourcesMitigation OptionsRelevant Linksgaz sf6 is widely used by producers, casters and recycling companies in the magnesium industry. A cover gas of dilute Sulfr hexafluoride in dry air and/or carbon dioxide (CO2) protects molten metal from oxidation and potentially violent burning. Without protection, molten magnesium will oxidize in the presence of air and form magnesium oxide (MgO) deposits that greatly reduce the quality and strength of the final product. In contrast, an effective cover gas, such as sf6 gas, modifies and stabilizes the MgO surface film to form a protective layer that prevents further oxidation. Studies conducted to characterize the reaction byproducts of sf6 gas and molten magnesium determined that most of the sf6 gas introduced to the molten metal surface is emitted to the atmosphere and that only a small portion reacts or decomposes. With a global warming potential (GWP) 22,800 times as strong as carbon dioxide (CO2) and a 3,200-year atmospheric lifetime, reducing sf6 gasemissions yields significant environmental benefits.
