Fluorite is also called fluorite. A common mineral in nature, which can be produced together with other minerals, is produced in many parts of the world, and there are five effective varieties. Equiaxed crystal system, the main component is calcium fluoride. Crystals are octahedrons and cubes. The crystal is glassy, colorful and fragile, with Mohs hardness of 4 and melting point of 1360℃, which has the property of perfect cleavage. Some samples can emit light under the conditions of friction, heating and ultraviolet irradiation. -Quoted from the Internet

Fluorite comes from the remnants of volcanic magma. Magma flowed into the ground when the volcano erupted. Magma contains a variety of organic and inorganic elements, and many gems in nature are born from magma. Fluorine ions in gas-water solution combine with calcium ions to form compound calcium fluoride, which is fluorite we see now. I have to praise the ingenuity of nature, and create a gem full of vitality. This kind of gem is common in volcanic eruption areas, and it is gradually discovered by people and becomes a kind of jewelry.

Fluorite is the only mineral that can extract a lot of fluorine. Can be widely used in industry. Steel will be mixed with a lot of impurities in the refining process, which will affect the hardness and toughness of steel. Fluorite can be used as a cosolvent to remove impurities and improve the quality and properties of steel.

In addition, it can also be used as a catalyst to promote chemical reactions in the production of glass and enamel. In the field of optics, fluorite can be made into lenses of various optical instruments, while lenses made of ordinary glass have smaller chromatic aberration. Good specimens can have a high price, but the appreciation is average, and they are often used as a foil for jewelry.
