Fluorite Treatments; The blue to deep blue to black color seen in some fluorites is derived from a color center, the F-center.This involves an electron-center precursor, and a missing fluorine atom in the fluorite, CaF 2.An electron liberated by irradiation or other processes (Nassau, 1983) from a hole-center precursor can be trapped at the fluorine vacancy to become the electron color-center.
Fluorite is used on a large scale to separate slag in steel-making. Mined fluorite (CaF 2) is a commodity chemical used in steel-making. Hydrofluoric acid and its anhydrous form, hydrogen fluoride, is also used in the production of fluorocarbons. Hydrofluoric acid has a variety of specialized applications, including its ability to dissolve glass.
