advantages of IR SF6 tanks pdf

Advantages and Disadvantages of SF6 Gas In its pure state SF6 gas is colorless, odorless, tasteless and non-toxic. At room temperature and pressure, it is gaseous and has a density of 6.16 g/l, about five times the density of air. Since its critical temperature is 45.6°C it can be liquefied by compression and is normally transported as a liquid.
