CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Industrial molten magnesium processes primarily utilize sulfur hexafluoride (sf 6) as a cover gas to inhibit surface oxidation, which can result in fires if not controlled. Recent concerns with global warming and subsequent research has determined SF6 to be a potent and long lived greenhouse gas.
