Sulfur hexafluoride

Sulfur hexafluoride is a colorless, odorless, nontoxic, nonflammable gas that has a high dielectric strength and serves widely as an insulating gas in electrical equipment. At atmospheric pressures it sublimes directly from the solid to the gas phase and does not have a stable liquid phase unless under a pressure of more than 32 psia (221 kPa, abs). It is shipped as a liquefied compressed gas at its vapor pressure of 298 psig at 70°F (2050 kPa at 21.1 0C).
One of the most chemically inert

A new generation of ultra-high voltage insulating dielectric materials. As a good gas insulator, it is widely used for gas insulation of electronic and electrical equipment. Electronic grade high purity sulfur hexafluoride is an ideal electronic etchant, widely used in the field of microelectronics technology, used as a plasma etching and cleaning agent in the manufacture of large integrated circuits such as computer chips and LCD screens. It is used as a fluorine source for the production of fluorine-doped glass in the preparation of optical fibers, and as a dopant in the isolation layer in the manufacture of low-loss high-quality single-mode optical fibers. It can also be used as a doping gas for nitrogen excimer lasers. Used as tracer, standard gas or mixed standard gas in meteorological, environmental testing and other departments. Used as an arc extinguishing and high-capacity transformer insulation material in high-voltage switches. It can also be used in particle accelerators and lightning arresters. Taking advantage of its good chemical stability and non-corrosive to equipment, it can be used as a refrigerant in the freezing industry (operating temperature-45 ~ 0 ℃). Due to the high stopping ability of alpha particles, it is also used in radiochemistry. In addition, it is used as a reverse adsorbent to displace oxygen from coal dust in mines. It can be used in the smelting and casting process of non-ferrous metals, as well as the degassing and purification of aluminum and its alloy melts. In the microelectronics industry, sulfur hexafluoride can be used to etch silicon surfaces and remove organic or inorganic films on semiconductor materials, and can be used as a single-film optical fiber isolation layer dopant during the manufacture of optical fibers. The current interrupter added with sulfur hexafluoride has a high rated voltage and is not easy to burn. In addition, sulfur hexafluoride is also used as an insulating medium for various accelerators, ultra-high voltage accumulators, coaxial cables and microwave transmission. At present, sulfur hexafluoride is a widely used tracer for measuring air pollution, with a tracer distance of up to 100km. Sulfur hexafluoride has good chemical stability and is not corrosive to equipment. It can be used as a refrigerant in the freezing industry (operating temperature is between -45 and 0°C). It can be used as a refrigerant to replace freon, which has no destructive effect on the ozone layer and is environmentally friendly. And performance requirements, is a refrigerant with great development potential. Used as a tracer for electrical insulation medium and arc extinguishing agent to determine the degree of atmospheric pollution. It is mainly used for arc extinguishing in high-voltage switches, and as an insulating material in large-capacity transformers and high-voltage cables. It can be used as a gas insulating material in nuclear particle accelerators and lightning arrester X-ray equipment. It has good chemical stability with SF6 and does not corrode the equipment. It can be used as a refrigerant in the freezing industry (operating temperature is between -45 ~ 0 ℃), SF6 has a high stopping ability for α-particles, so it is also used in radiochemistry; it can also be used as a reverse adsorbent to replace oxygen from coal dust in mines. Used as a gas insulator for electronic equipment and radar waveguides.
