    Sulfur hexafluoride is a compound having the formula gaz sf6. At normal room temperatures and pressures (20 °C and 100 kPa) [1]1 it is gaseous and has a density of 6,07 kg/m3 (about five times the density of air). Since its critical temperature is 45,54 °C, it can be liquefied by compression [2].
