Hexafluorosulfide

Sulfur hexafluoride is a unique gas due to its chemical inertness and stability.

Chemical Formula: SF₆

Layman's explanation: Sulfur hexafluoride was discovered in the 1950s by scientists who had just recently isolated the similiar compound of SF4. Sulfur hexafluoride is a colorless, odorless, nontoxic, nonflammable, and noncorrosive gas at room temperature. It immediately sublimes from a solid into a gas at atmospheric pressures, and only becomes reactive at extremely high temperatures. Sulfur hexafluoride is useful in the semiconductor industry, such as in transformers, condensers, and circuit breakers, due to the fact that it does not conduct electricity and yet has dielectric properties. It is also used in leak detection and as an etchant.
