10 L Cylinder Packed Sulphur Hexafluoride Sf6 150-200 Bar Filfilling Pressure
SF6 gas has a hundred years of history, it is the French two chemists Moissan and Lebeau in 1900 synthesis, 1947 to provide commercial use. Sulfur hexafluoride is a volatile compound. Brownish brown at room temperature, red and brown when liquid and gaseous. Strong alpha radioactivity. Melting point 50.75 ° C. The boiling point of 62.3 ℃. Under normal pressure does not sublimate, but with the different uranium hexafluoride, from the liquid into a gaseous. Is a strong oxidizing agent. Trace amounts of water vapor quickly hydrolyze it into fluorinated plutanyl (PuO2F2). Pure SF6 gas is a colorless, odorless, basic non-toxic, non-combustible halogen compounds. The relative density is 6.16 g / cm3 (20 ° C, 0.1 MPa) in the gaseous state and 1400 g / cm3 (at 20 ° C) in the liquid state. SF6 gas is very stable in the air, does not burn in the air, does not help combustion, and water, alkali, ammonia, hydrochloric acid, sulfuric acid and other non-reaction; at less than 150 ℃, SF6 gas was chemically inert, , Slightly fused to alcohol.

SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble.SF6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein.
Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing.
