High purity sulfur hexafluoride has good electrical insulation performance and excellent arc extinguishing performance.Sulfur hexafluoride can be used as a reverse adsorbent in the mining industry,and coal dust can be used to replace oxygen.

　　As one of the important greenhouse gases,high purity sulfur hexafluoride is mainly used in electronic manufacturing,electrical equipment,metal smelting and atmospheric tracing.As an important consumption industry of sulfur hexafluoride,the use of sulfur hexafluoride gas has been basically stopped in the electronic manufacturing industry and atmospheric tracing industry in order to meet the requirements of environmental protection through research and technological improvement.

　　High purity sulfur hexafluoride also because of chemical inert,non-toxic,non-combustible and non-corrosive,is widely used in metal smelting,aerospace,medical(X-ray machine,laser machine),meteorological(tracer analysis),chemical(***automobile tires,new fire extinguishers)and so on.In metal smelting,the amount of high-purity sulfur hexafluoride has been substantially reduced through the use of gas mixtures,and improvements are ongoing.

　　Nowadays,the voice of environmental protection concern of sulfur hexafluoride gas is gradually increasing in China.As a large consumption of electrical equipment,electrical equipment itself is also constantly expanding the application of new technology of sulfur hexafluoride equipment.
