High Purity Sulfur Hexafluoride Gas Sf6 Used In Microelectronic Technology

 

 

Description:

 

SF6 gas has a history of more than a hundred years. It was a synthetic inert gas synthesized by French chemists Moissan and Lebeau in 1900 and used by the U.S. military for the Manhattan Project (nuclear military) around 1940. 1947 available commercially.

 

The current SF6 gas is mainly used in the power industry. SF6 gas is used for 4 types of electrical equipment as insulation and / or arc suppression; SF6 circuit breakers and GIS (here referred to as SF6 enclosed electrical appliances, internationally known as "Gas Insulated Switchgear" )), SF6 load switchgear, SF6 insulated transmission line, SF6 transformer and SF6 insulated substation. 80% for high and medium voltage power equipment.

Applications:

 Electrical Industries Circuit Breaker

  leak detection and as a gaseous dielectric for transformers, condensers
and circuit breakers,high-voltage transmission line, CIS, large cable coil, mutual    inductor, lightning arrester.

 

 As an inert gas

 

 For the casting of magnesium.as an etchant in the semiconductor
industry

 

 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.
