Fluorite is also called fluorspar. Its main component is CaF2, which is the main source of fluorine(F)in industry. In the glass industry, fluorite is added as a cosolvent and sunshade, which can promote the melting of glass materials. Different glass, the amount of fluorite added is different.

1. Ordinary glass sheet, fluorite content is 1% of the charge;

2. Alkaline glass spheres, fluorite content is 12%;

3. Oxidized glass, fluorite content is 3%;

4. In the production process of white, milky and colored glass, fluorite is not only used as a co-solvent, but also as a sunshade, and the amount added is 10-20% of the furnace charge.

The quality of fluorite in glass industry is more strict, requiring CaF2>80; Fe2O3<0.2.

Other Main Application

(1)Metallurgical industry

It is widely used as a flux in smelting iron, Iron alloy production and non-ferrous metal smelting. Fluorite can reduce the melting point of the slag to promote the flow of a good separation of the slag and metal desulphurization in the smelting process.

(2)Chemical industry

Another important use of fluorite is to produce hydrofluoric acid. It is the key raw materials to produce a variety of organic and inorganic fluoride and fluorine.

(3)Other Uses

*Fluorite has dense structure, varied colorful. It can be used as carving material.

*Optical fiber conduction and high-precision fields.

*Electrical and electronic appliances

*Lithium batteries and pharmaceuticals, polymers and agrochemicals
