Sulfur hexafluoride finds application as an etching gas in MEMS and flat-panel production due to its large molecule size and high density. The high reactivity and energy of SF6 ions provide an enhanced etching rate. As a result, the demand for SF6 in these applications is expected to witness growth over the forecast period. UHP grade sulfur hexafluoride is majorly used in the manufacturing of electronic appliances and non-invasive medical surgeries.
