  2. Fluorite - Wikipedia

    en.wikipedia.org/wiki/Fluorite

    Natural fluorite mineral has ornamental and lapidary uses. Fluorite may be drilled into beads and used in jewelry, although due to its relative softness it is not widely used as a semiprecious stone. It is also used for ornamental carvings, with expert carvings taking advantage of the stone's zonation.

  3. 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.

    Powers machinery in Atlantis in the video game Indiana Jones and the Fate of Atlantis. In Exalted, Orichalcum is the strongest of the five magical materials and can be made by distilling ordinary gold using Gaia's blood (Magma) and concentrating sunlight using large occult mirrors. Found in Final Fantasy as a rare material with varying properties.

  5. Chlorophane - Wikipedia

    en.wikipedia.org/wiki/Chlorophane

    Chlorophane, also sometimes known as pyroemerald, cobra stone, and pyrosmaragd, is a rare variety of the mineral fluorite with the unusual combined properties of thermoluminescence, thermophosphoresence, triboluminescence, and fluorescence: it will emit light in the visible spectrum when exposed to ultraviolet light, when heated, and when ...

  6. Water fluoridation - Wikipedia

    en.wikipedia.org/wiki/Water_fluoridation

    Water fluoridation is the controlled addition of fluoride to public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. [2] In the mouth, fluoride slows tooth enamel demineralization and enhances remineralization in early-stage cavities ...

  7. Cryolite - Wikipedia

    en.wikipedia.org/wiki/Cryolite

    Substantial energy is still needed for both heating the materials and the electrolysis, but it is much more energy-efficient than melting the oxides themselves. As natural cryolite is now too rare to be used for this purpose, synthetic sodium aluminium fluoride is produced from the common mineral fluorite. [citation needed]

  8. Fluorochemical industry - Wikipedia

    en.wikipedia.org/wiki/Fluorochemical_industry

    The modern version of the process uses steel containers as cathodes, while blocks of carbon are used as anodes. The carbon electrodes are similar to those used in the electrolysis of aluminium. An earlier version of fluorine production process, by Moissan, uses platinum group metal electrodes and carved fluorite containers. The voltage for the ...

  9. 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 ...
