Description

Sulfur hexafluoride is an inorganic compound. It is a colorless, odorless, non-toxic and non-flammable stable gas under normal temperature and pressure. It has good electrical insulation properties and excellent arc extinguishing properties.

 

Typical Application:

‌Electrical Field

Sulfur hexafluoride gas is widely used in high-voltage electrical equipment due to its excellent electrical insulation properties and strong electronegativity. Its insulation capacity is 2.5 times that of air, and its arc extinguishing capacity is 100 times that of air. Therefore, it is used as an insulating and arc extinguishing medium in high-voltage switches, transformers, mutual inductors, capacitors and other equipment to ensure the safe operation of equipment under high voltage and reduce the occurrence of equipment failures and power outages.

‌Industrial Production Field

Sulfur hexafluoride gas has a variety of applications in metal smelting and semiconductor manufacturing. In metal smelting, it is used as a protective gas to prevent metals from reacting with oxygen at high temperatures and improve the quality and purity of metals. In semiconductor manufacturing, sulfur hexafluoride can be used as an etching gas and cleaning agent to precisely control the size and shape of semiconductor devices and remove impurities and pollutants on the surface.

‌Meteorological and Environmental Monitoring Field

Since sulfur hexafluoride is non-toxic, safe, and stable in nature, it is often used as a gas tracer to help study phenomena such as atmospheric circulation and pollutant diffusion.

‌Medical field

Sulfur hexafluoride is used in ultrasound angiography. As a safe contrast agent, it dissolves in the blood after intravenous injection and is used for contrast examination of diseases such as liver tumors to improve diagnostic accuracy.

‌Scientific research field‌

In some special laboratories and scientific research projects, sulfur hexafluoride may be used as a special gas medium to meet specific experimental needs.

‌Refrigeration industry

Sulfur hexafluoride has good chemical stability, is harmless to the ozone layer, has certain refrigeration performance, and can be used as a refrigerant to replace Freon for low-temperature refrigeration systems.
