Description and Uses
Fluorine is a highly toxic, pale yellow gas about 1.3 times as heavy as air at atmospheric temperature and pressure. When cooled below its boiling point (-306.8°F or -188.2°C), it is a liquid about 1.5 times as dense as water.
In manufacture of UF6 for nuclear power generation, of SF6 for dielectrics, of fluorinating and metal fluoride compounds.
