Decomposition of sf6 gas in an RF Plasma Environment

sf 6 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 insulating gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf6 gas 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 oxygenGet price
