Fluorescent, also known as calcium fluoride, is a common halide mineral. It is a compound whose composition is calcium fluoride and is an important mineral for extracting fluorine. Fluorescent has many colors and can also be transparent and colorless. Transparent colorless fluorite can be used to make special optical lenses. Fluorescent also has many uses, such as as as a flux for steel and aluminum production, for the manufacture of milky white glass, enamel products, catalysts for high-octane fuel production, and so on. Fluorescent is generally granular or blocky, with a glass luster and more green or purple. Fluorescent often emits blue-green fluorescence under ultraviolet or cathode radiation, and its name is based on this feature.

Main application：
The use of fluorite is very extensive. With the Advancement of science and technology, the application prospects are becoming more and more broad. At present, it is mainly used in the metallurgical industry to produce raw materials for aluminum-smelter cryolite, raw materials for hydrofluoric acid, leflon salts and refrigerants in the chemical industry, and decorative materials for the building materials industry, followed by light industry, optics, and sculpture. And defense industry. Therefore, according to the requirements of use, there are four major series of fluorite minerals in China, namely fluorite, fluorite, fluorite and optical and carved fluorite.
Application Fields：
Fluorescent is widely used in the glass, ceramics, cement and other building materials industry, and its usage accounts for the second place in China.
Crystal structure: The cell is a face-centered cubic structure, each cell contains 4 calcium
ions and 8 fluorine ions.
Crystal state: crystalline bodyCrystal habits: often cube, octahedron, diamond dodecahedron and polymorphic, can also
be a strip dense block aggregate.
Common colors: green, blue, brown, yellow, pink, purple, colorless, etc..Ultraviolet fluorescence: varies with different species, generally with a strong fluorescence,
can have phosphorescence.
Absorption spectrum: not characteristic, change big, general strong absorption.Enlarged examination: Colors, two-phase or three-phase inclusion, visible cleavage in
a triangular development.
Special optical effect: discoloration effect.Heat treatment: often black, dark blue heat treatment blue, stable, avoid heat above 300 °C,
not easy to detect.
Fractures: Fractures are filled with plastic or resin to ensure that they do not break during processing.
