Sulfr hexafluoride gas in medium-voltage switchgear | TD - Siemens USA

sf6 gas usage Sulfr hexafluoride has been used extensively in non-electrical applications. Since sf 6 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.Get price

Decomposition of sf 6 in an RF Plasma Environment

Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η gaz sf6 was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-duced the electron density and, thus, reduced the dis-sociation of SF 6 and inhibited the production ofGet price
