| Description |
Pale yellow gas, most reactive of all elements and the
strongest commercially available oxidant. Produced by electrolysis of
molten KF2HF. Used to make UF6, SF6 and
fluorinating agents such as ClF3. Organic compounds, polymers
and salts all used as flux in metallurgy and aluminum making. Diagnostic tests:
A sample of the mineral heated in a closed tube with potassium bisulfate (KHSO4) and
powdered glass, produces a white sublimate of SiO2 due to the
formation of volatile SiF4.
