THERMAL DECOMPOSITION OF gaz sf6 AND gaz sf6-AIR MIXTURES IN

Jan 01, 2013 · What causes the decomposition of sulfur fluoride on glass is the presence of H 2 0. The surface of the glass separator is always kept under vacuum in a flow of dried helium gas. So, the catalytic effect of "absent" H 2 0 should not occur. 419 K. BAUCOM: S0 2 and SOF2 can react with F 2 to form S0 2 F 2 and SOF4, respectively.Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price
