2. Fluorite - Wikipedia

   en.wikipedia.org/wiki/Fluorite

   Pure fluorite is colourless and transparent, both in visible and ultraviolet light, but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels.

3. Fluorite structure - Wikipedia

   en.wikipedia.org/wiki/Fluorite_structure

   The fluorite structure refers to a common motif for compounds with the formula MX 2. [1] [2] The X ions occupy the eight tetrahedral interstitial sites whereas M ions occupy the regular sites of a face-centered cubic (FCC) structure. Many compounds, notably the common mineral fluorite (CaF 2), adopt this structure.

4. History of fluorine - Wikipedia

   en.wikipedia.org/wiki/History_of_fluorine

   The word "fluorine" derives from the Latin stem of the main source mineral, fluorite, which was first mentioned in 1529 by Georgius Agricola, the "father of mineralogy". He described fluorite as a flux—an additive that helps melt ores and slags during smelting. [1] [2] Fluorite stones were called schone flusse in the German of the time ...

5. Fluoride - Wikipedia

   en.wikipedia.org/wiki/Fluoride

   The main uses of fluoride, in terms of volume, are in the production of cryolite, Na 3 AlF 6. It is used in aluminium smelting. Formerly, it was mined, but now it is derived from hydrogen fluoride. 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.

6. Biological aspects of fluorine - Wikipedia

   en.wikipedia.org/wiki/Biological_aspects_of_fluorine

   Though elemental fluorine (F 2) is very rare in everyday life, fluorine-containing compounds such as fluorite occur naturally as minerals. Naturally occurring organofluorine compounds are extremely rare. Man-made fluoride compounds are common and are used in medicines, pesticides, and materials.

7. Fluorine - Wikipedia

   en.wikipedia.org/wiki/Fluorine

   Fluorite, the primary mineral source of fluorine, which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb fluo meaning ' to flow ' gave the mineral its name. Proposed as an element in 1810, fluorine proved difficult and dangerous to separate from its ...
