From the appearance, Calcium Fluoride CaF2 is a white crystal, hardly soluble in water. From a microscopic point of view, the crystal structure of Calcium Fluoride CaF2 is a cube. Calcium ions and fluoride ions coordinate in a cubic form, and fluoride ions coordinate with four calcium ions in a tetrahedral form. The presence of fluorine in the lattice center makes Calcium Fluoride in minerals Fluoride CaF2 has a very dark color.

Of course, the use of fluorite in industry is not only as simple as night pearl, it has many uses in metallurgy, chemical industry and building materials and other industries

Desiccant: used for drying nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases.

Dehydrating agent: used in the production of alcohol, ester, ether and acrylic resin.

Refrigerant: Calcium chloride aqueous solution is used for refrigeration to make ice;

Antifreeze: accelerate the hardening of concrete and increase the cold resistance of building mortar

Deinking agent: It is used for deinking of waste paper processing, and it is also a raw material for the production of calcium salt.

In addition, it should be reminded that Calcium Fluoride CaF2 is a toxic substance and should be stored in a ventilated, low-temperature and dry environment.
