A review on insulating gas substitute gases and research status of CF3I

Nov 01, 2018 · Yokomizu et al. from Nagoya University Japan investigated high-temperature plasma of CF 3 I/CO 2. They determined that the conductivity of CF 3 I/CO 2 increases with the increase of CF 3 I when the temperature is below 10 kK. Its thermal conductivity is related to CF 3 I when the temperature is approximately 7000 K.

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 of
