Cylinder Gas High Purity 99.999% Sf6 Use in the Electric Power Industry
Description:
Nonelectrical uses include molten magnesium and aluminum protection
and purification, leak
detection, tracer gas studies, propellants, insulating windows,
shock absorbers, lasers and in the
electronics industry as a plasma etchant gas.
The other 20% of the annual consumption of SF6 is
used in these applications which typically require release of the
gas into the atmosphere.

Applications:
Electrical Industries Circuit Breaker | leak detection and as a gaseous dielectric for transformers,
condensers |
As an inert gas | For the casting of magnesium.as an etchant in the semiconductor |
As an inert filling | Insulated glazing windows. |
Dielectric medium | 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. |
Medical use | 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. |
Tracer compound | 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. |
