High purity sulfur hexafluoride colorless,tasteless,non-combustible,no electrical resistance,relatively non-toxic.The pressure of a liquefied bottled gas is its vapor pressure.With its good insulation performance and arc extinguishing performance,it is widely used in the electrical industry,such as:circuit breaker,high voltage switch,high voltage transformer,gas closed combination capacitor,high voltage transmission line,transformer and so on.Also because of its chemical inert,non-toxic,non-combustible and non-corrosive,is also widely used in metal smelting,aerospace,medical,meteorological,chemical industry,etc.

　　Electron grade high purity sulfur hexafluoride is an electron etching agent used in microelectronics.With the development of science and technology,the fields involved in SF6 continue to expand,and is widely used in more and more basic fields and scientific and technological fields.In the refrigeration industry,sulfur hexafluoride is used as refrigerant,and the cooling range can be between-45℃~0℃.

　　For example,a circuit breaker is a circuit breaker that uses high-purity sulfur hexafluoride as the arc extinguishing medium and insulating medium.Due to the excellent characteristics of the gas,the single break of the circuit breaker is much higher than that of the compressed air circuit breaker and the less oil circuit breaker in terms of voltage and current parameters,and does not require high air pressure and a considerable number of series breaks.

　　At the same time also used as magnesium aluminum alloy die casting protection gas.Sulfur hexafluoride gas as an ideal electron etching gas is widely used in the field of microelectronics.As a dopant of single film fiber isolation layer in optical fiber manufacturing.Air pollution monitoring,hydrogeological detection in the field of tracer.Contrast-enhanced ultrasonography of liver tumors is also used as a contrast medium.
