    Clothing used by the person burned may also present a danger. [63] Hydrofluoric acid exposure is often treated with calcium gluconate, a source of Ca 2+ that binds with the fluoride ions. Skin burns can be treated with a water wash and 2.5 percent calcium gluconate gel [64] [65] or special rinsing solutions. [66]

  3. 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.

  4. Fluoride - Wikipedia

    en.wikipedia.org/wiki/Fluoride

    Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion.

  5. 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 ...

  6. History of fluorine - Wikipedia

    en.wikipedia.org/wiki/History_of_fluorine

    Fluorine is a relatively new element in human applications. In ancient times, only minor uses of fluorine-containing minerals existed. The industrial use of fluorite, fluorine's source mineral, was first described by early scientist Georgius Agricola in the 16th century, in the context of smelting.

  7. Natural skin care - Wikipedia

    en.wikipedia.org/wiki/Natural_skin_care

    Natural skin care uses topical creams and lotions made of ingredients available in nature. [1] Much of the recent literature reviews plant-derived ingredients, which may include herbs , roots , flowers and essential oils , [ 2 ] [ 3 ] [ 4 ] but natural substances in skin care products include animal-derived products such as beeswax , and minerals.

  8. Sodium fluoride - Wikipedia

    en.wikipedia.org/wiki/Sodium_fluoride

    Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.

  9. Origin and occurrence of fluorine - Wikipedia

    en.wikipedia.org/wiki/Origin_and_occurrence_of...

    Fluorapatite (Ca 5 (PO 4) 3 F) is mined along with other apatites for its phosphate content and is used mostly for production of fertilizers. Most of the Earth's fluorine is bound in this mineral, but because the percentage within the mineral is low (3.5%), the fluorine is discarded as waste. Only in the United States is there significant recovery.
