Although selenium hexafluoride is quite inert and slow to hydrolyze, it is toxic even at low concentrations, [9] especially by longer exposure. In the U.S., OSHA and ACGIH standards for selenium hexafluoride exposure is an upper limit of 0.05 ppm in air averaged over an eight-hour work shift.
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
Selenium dichloride is an important reagent in the preparation of selenium compounds (e.g. the preparation of Se 7). It is prepared by treating selenium with sulfuryl chloride (SO 2 Cl 2 ). [ 10 ] Selenium reacts with fluorine to form selenium hexafluoride :
Hexafluoride-forming elements Octahedral structure of SF 6. Seventeen elements are known to form binary hexafluorides. [2] Nine of these elements are transition metals, three are actinides, four are chalcogens, and one is a noble gas. Most hexafluorides are molecular compounds with low melting and boiling points.
