Application:
1.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 that can contain harmful PCBs.
2.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.
3.Tracer compound:
Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration. It has been used successfully as a tracer in oceanography to study diapycnal mixing and air-sea gas exchange.
