Fluoride Wikipedia
OverviewNomenclatureOccurrenceChemical propertiesApplicationsDietary recommendationsFluoride is an inorganic, monatomic anion with the chemical formula F−, whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. 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...

Fluorite Wikipedia

Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2.It belongs to the halide minerals.It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as Fluorite.. Pure fluorite is transparent, both in visible and ultraviolet
