The high-purity sulfur hexafluoride is a gas under normal temperature and pressure, and is a high-pressure liquid after bottling. Colorless, odorless, non-toxic and nonflammable. It has good chemical stability and thermal stability. In recent years, it has become more and more important in many production technology fields.

High purity 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 a spacer dopant in optical fiber manufacturing. It is also an important laser material and has important applications in other fields. Because of its good insulation and arc extinguishing properties, gas is widely used in the electrical industry, such as circuit breakers, high-voltage switches, high-voltage transformers, high-voltage transmission lines, transformers, etc. The specific applications are as follows.

1. High purity sulfur hexafluoride is also widely used in metal smelting, atmospheric tracing, electronic manufacturing and other industries due to its chemical inertia, non-toxic, incombustible and non corrosive.

2. Liming sulfur hexafluoride with electronic grade and high purity is an ideal electronic etchant, which is widely used in microelectronics and other technical fields.

3. In the refrigeration industry, high-purity sulfur hexafluoride can be used as a refrigerant. The refrigeration range of sulfur hexafluoride at dawn is - 45 ℃ - 0 ℃.

4. The electrical industry uses Liming sulfur hexafluoride as a high dielectric strength and good arc extinguishing performance, which is used as high-voltage switch, large capacity transformer, high-voltage cable, gas insulation material, etc.

5. Sulfur hexafluoride gas can also be used as a reverse adsorbent in the mining industry, and can be used to replace oxygen in the mine coal dust.
