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

Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of sf 6Chemical Properties of gaz sf6 GasElectrical Properties of insulating gas Gassf 6 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

Gas density monitors and gas density sensors for gaz sf6 and

Trafag gas monitoring devices measure the gas density directly, i.e. sf 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. sf 6 Gas Density Sensors, or by combining both principles, i.e.sf6 gas Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring thesf 6 gas density.Get price

Density of air - Wikipedia

At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft 3. The following table illustrates the air density–temperature relationship at 1 atm or 101.325 kPa:Get price
