Sulfur Hexafluoride Greenhouse Gas - China

price: contact company for price

SF6 has an octahedral geometry, consisting of six fluorine atoms

attached to a central sulfur atom. It is a hypervalent molecule. Typical

for a nonpolar gas, it is poorly soluble in water but soluble in

nonpolar organic solvents. It is generally transported as a liquefied

compressed gas. It has a density of 6.12 g/L at sea level conditions,

which is considerably higher than the density of air (1.225 g/L).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 gas under pressure is used as an insulator in gas

insulated switchgear (GIS) because it has a much higher dielectric

strength than air or dry nitrogen.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. It is inert in the vitreous chamber and initially

doubles its volume in 36 hours before being absorbed in the blood in 10-

14 days.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.SF6 plasma is also used in the

semiconductor industry as an etchant. SF6 breaks down in the plasma into

sulfur and fluorine, the fluorine plasma performing the etching.

The magnesium industry uses large amounts of SF6 as inert gas to fill casting forms.

Sulfur hexafluoride is also used to pressurize waveguides in radar systems. The gas insulates the waveguide preventing internal arcing. The same use of sulfur hexafluoride is applied in transmission waveguides of medical linear accelerators, which are used for delivery of external beam radiotherapy.

Sulfur hexafluoride has been used in electrostatic loudspeakers because of its high dielectric strength and high molecular weight.

Sulfur hexafluoride has been used to fill tyres of racing cars in professional events due to its non-flammability and high density.
