Fluorite ( also called fluorspar) is a halide mineral composed of calcium fluoride、 caf2. it is an isometric mineral with a cubic habit、 though octahedral and more complex isometric forms are not uncommon。 crystal twinning is common and adds complexity to the observed crystal habits。
The word fluorite is derived from the latin root fluo、『 meaning to flow" because the mineral is used to increase the fluidity of slags used in smelting flux。 this increase in fluidity is the result of the ionic nature of the mineral。 the melting point of pure calcium fluoride is 1676 k。 in 1852 fluorite gave its name to the phenomenon of fluorescence、 which is prominent in fluorites from certain locations、 due to certain impurities in the crystal。 fluorite also gave the name to its constitutive element fluorine。
Flourite is a colorful mineral、 both in visible light and often under ultraviolet、 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。 the purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture、 which is the intermediate source of most fluorine- containing fine chemicals。 optically- clear transparent fluorite lenses have low dispersion、 so lenses made from it exhibit less chromatic aberration、 making them valuable in microscopes and telescopes。 fluorite optics are also usable in the far- ultraviolet range where conventional glasses are too absorbent for use。
Industrial grades there are three principal types of industrial use for natural fluorite、 corresponding to different grades of purity。 metallurgical grade fluorite、 the lowest of the three grades、 has traditionally been used as a flux to lower the melting point of raw materials in steel production to aid the removal of impurities、 and later in the production of aluminium。 ceramic ( 中間) grade fluorite is used in the manufacture of opalescent glass、 enamels and cooking utensils。 the highest grade、『 acid grade fluorite" ( 97％ or more caf2)、 is used to make hydrogen fluoride and hydrofluoric acid by decomposing the fluorite with sulfuric acid。
