Decomposition of gaz sf6 in an RF Plasma Environment

gaz sf6 clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η Sulfr hexafluoride 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-Get price
