Hexafluoride refers to a chemical compound that contains six fluorine atoms bonded to a central atom. One of the most well-known examples is sulfur hexafluoride (SF₆), which is used in electrical insulation and in various industrial applications due to its excellent dielectric properties. Hexafluorides are typically colorless, odorless gases at room temperature. These compounds are notable for their high stability and low reactivity, making them useful in specific applications. However, some hexafluorides, like nitrogen trifluoride (NF₃), are potent greenhouse gases, contributing to climate change. Proper handling and regulation are essential to minimize their environmental impact.
