Colourless in-noxious and non-flammable gas at atmospheric temperature, sulfur hexafluoride is actually one of the most stable gaseous chemicals.
Sulfur hexafluoride, or SF6 as it’s usually named, is a heavy, inert, nontoxic and incombustible gas.
Its main uses are as an insulation medium in electrical transmittance systems and electrical distributing devices, making an inert cover, or simply for displacing the gas mixtures in metals smelting.
Colourless in-noxious and non-flammable gas at atmospheric temperature, with a molecular weight of 146.06, the density of SF6 gas is 6.139 g/l (20oC) and is almost five times as much as that of air (1.29 g/l).
