Theoretical study of SF6 decomposition on the MoS2

Sulfur hexafluoride (SF6) is an important gas for plasma etching processes in the semiconductor industry. SF6 intensely absorbs infrared radiation and, consequently, aggravates global warming.

WO1998012360A1 - Process for refining high-impurity copper

A process for refining high-impurity blister copper to anode quality copper is disclosed. In an oxidation step of a blister copper refining stage, soda ash fluxing removes antimony and arsenic while also removing sulfur and iron. In a deoxidation step of the blister copper refining stage, sulfur hexafluoride is injected at a controlled oxygen concentration to remove bismuth while reducing the

Materials Used in Solar Panels

Silicon production reactors are cleaned with sulfur hexafluoride, which is the most potent greenhouse gas per molecule according to the Intergovernmental Panel on Climate Change. It also can react with other chemicals to produce sulfur dioxide, which is responsible for acid rain.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
