The molecular formula for sulfur hexafluoride is F6S, which means that it has one sulfur atom and six fluorine atoms. It is a synthetic gas that is primarily used in electrical transmission equipment such as circuit breakers.
Sulfur hexafluoride is a man-made gas that is odorless, colorless, non-flammable and water-soluble. Additionally, the EPA has determined that it has the greatest potential negative impact on the environment among all greenhouse gases. Over a 100-year period, the potential global environmental impact of sulfur hexafluoride is more than 22,000 times the potential impact of carbon dioxide. However, the ratio of the gas in the atmosphere is minimal, preventing it from significantly contributing to global warming.
