SF6 gas or sulfur hexafluoride gas is a colorless and odorless gas. Inhalation of sulfur hexafluoride gases in high concentrations causes suffocation. This gas is much heavier than air and is classified as a greenhouse gas. The greenhouse effect of this gas is far greater than the greenhouse effect of carbon dioxide.
Purity types of sulfur hexafluoride gas
 

SF6 gas can be supplied with different purity
Grade 3 SF6 gas with a purity of about 99.9%
SF6 gas grade 4.5 with 99.995% purity
SF6 gas grade 4.8 with 99.9998% purity
Grade 5 SF6 gas with 99.9999% purity
Properties of sulfur hexafluoride gases
Now let's talk about the features and characteristics of Sf6 gas. This gas is a type of mineral compound. This gas is considered among greenhouse gases. Its molecular geometry is hexahedral, and as it is clear from its formula, it consists of 6 fluorine atoms and one sulfur atom, which is placed in the center of 6 other atoms. This substance is non-polar and therefore it is difficult to dissolve in water and can be soluble in non-polar solvents. For transportation, it is compressed into a liquid gas. This gas is up to 5 times heavier and denser than air and is known as a non-reactive substance due to the filling of all reactive capacities. This gas can prevent ignition at high voltage.
Applications of SF6 gas
One of the main uses of SF6 gas is to use it as an environmental dielectric, insulation in circuit breakers, gears and electrical substations, and this is the use of SF6 gas in the electrical industry. In order for this gas to be used as a dielectric, it must meet ASTM D2472 and IEC standards. Sulfur hexafluoride gas is used to fill double-glazed windows in order to reduce sound transmission and heat transmission. Double-glazed windows produced with this gas have a much higher efficiency than ordinary air and other gases.
In some chemical lasers, this gas is used as a source of fluorine, these types of lasers are usually found in research and development departments. Due to its high density, sulfur hexafluoride gas is used to coat molten metals such as magnesium in play baths. SF6 gases are also used in laboratories as a carrier gas in supercrystalline liquid chromatography (SFC) and as a medium in supercritical fluid extraction (SFE) for sample preparation. SF6 gas is listed in Japan's Kyoto Protocol, aiming to reduce greenhouse gas production. The medical applications of this gas include retinal surgery.
Sulfur hexafluoride gas production source
SF6 gas is produced by direct fluorination of pure sulfur. Generally, this gas is produced by fluorine producing companies for other purposes such as producing fluorine and carbons. To obtain this gas with higher purity, producers perform further purification steps such as distillation. The molecular weight of the gas is 146.06 g/mol. Its boiling point at atmospheric pressure is -63.9 degrees Celsius.
SF6 gas safety information
The large difference in the density of SF6 gas, like helium gas, can affect the frequency of vocal cords in the production of sound vibrations. For this reason, there may be people who inhale this gas for fun to change their voice. This gas is the opposite of helium. That is, it causes the vibration of the vocal cords to decrease and the frequency of the sound, while helium, on the contrary, causes it to increase. Breathing this gas, like any oxygen-free gas, can lead to the risk of suffocation and death, and it is recommended that people avoid this. Because the lack of oxygen can also lead to the risk of brain damage.
