Sulfur Hexafluoride (sf 6) electronic grade | Solvay

sf6 gas is applied in the above process as an etching gas. Due to the density and large molecule size, insulating gas is a preferred etching gas in flat panel and MEMS production processes. Fluorinated gases, such as Sulfur Hexafluoride (Sulfr hexafluoride), play very important roles in the manufacturing of silicon devices.Get price

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