Introduction to fluorite and its forming principle

Fluorite is also called Fluorite, Fluorite powder, Fluorite powder. Is a mineral, equiaxed crystal system, its main component is calcium fluoride (CaF2). Containing many impurities, Ca is often replaced by Y and Ce and other rare earth elements. In addition, it also contains a small amount of Fe2O3, SiO2 and a small amount of Cl, O3 and He.

Fluorescents in nature are often brightly colored, and some fluoresce. Mohs hardness 4, lower than steel, easy to scratch, brittle, sweet, astringent, non - toxic. Melting point: 1270-1350 ℃. Density: 3.18g/cm cubed, refractive index: 1.434.

Fluorite from volcanic magma, in the process of magma cools, the aqueous solution by magma isolated gas contains many substances, with fluoride is given priority to, in the process of solution along the fracture, the temperature is reduced, the pressure is reduced, air fluoride ion in aqueous solution combined with calcium ions in the surrounding rocks, forming calcium fluoride, get the fluorite after cooling crystallization.

It is a secondary mineral of granite, pegmatite and orthoclase, and fluorite can also be found in the jet holes around the volcano. They are also found in carbonate and alkaline intrusive rocks. It is deposited in hydrothermal vein and strata-controlled deposits. Fluorite ACTS as a binder at the natural junction of sandstone.
