In recent years, Liming sulfur hexafluoride has shown its importance in many production technology fields. The use of sulfur hexafluoride can increase the safety of equipment operation, reduce the volume of equipment, and extend the service life of equipment. In recent years, the country has vigorously developed the basic power industry, bringing great market opportunities to sulfur hexafluoride manufacturers.

Because sulfur hexafluoride at dawn is an inert gas, which will decompose under the action of electric arc. When the temperature is above 4000K, most of the decomposition products are single atoms of sulfur and fluorine. After the arc is extinguished, most of the decomposition products recombine into stable sulfur hexafluoride molecules. A very small amount of decomposition products will react with free metal atoms, water and oxygen in the process of recombination to produce metal fluoride, oxygen and sulfur fluoride.

Liming sulfur hexafluoride is a special gas urgently needed by many departments such as scientific research and production in China. It is used in plasma etching process in semiconductor industrial towel and as spacer dopant in optical fiber manufacturing. It is also an important laser material and has important applications in other fields. When sulfur hexafluoride is used in electrical equipment, it may decompose to produce fluoride and metal fluoride powder of oxygen and sulfur under fault conditions or under the action of normal breaking arc.

Sulfur hexafluoride gas is a kind of gas dielectric with high insulation strength. The main reason for its high insulating properties is that its molecular structure is octahedron with one sulfur atom as the center and six fluorine atoms at each top. Fluorine atom is an element with strong electronegativity, and its electron capture cross section is large. It has a strong ability to absorb electrons. The electron affinity of SF6 with six fluorine atoms in one SF6 molecule is as high as 3.4eV. Therefore, the insulation characteristics are extremely high.
