Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas.Get price

History of insulating gasChemical Properties of sf6 gas GasElectrical Properties of gaz sf6 GasSulfr hexafluoride or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that sf 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...Get price

gaz sf6 Gas Properties

It is about five times heavier than air, and has a density of 6.1 4kg / m3. It is colorless, odorless and non-toxic. Tests have been carried out replacing the nitrogen content of air by Sulfr hexafluoride (the gaseous mixture consisted of 79 % Sulfr hexafluoride and 24 % oxygen): five mice were then immersed in this atmosphere for 24 hours, without feeling any ill effects.Get price
