• Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

    gaz sf6 has been used extensively in non-electrical applications. Since gaz sf6 is inert, it is very attractive to the magnesium industry. Magnesium reacts spontaneously in the presence of oxygen, so a heavier-than-air cover gas is used to isolate the molten magnesium from oxygen as the magnesium cools.
