Calcium fluoride
Calcium fluoride (CAS 7789-75-5), with the molecular formula CaF2 and a molar mass of 78.07 g/mol, is an inorganic salt that occurs naturally as the mineral fluorite. It is a white crystalline powder known for its low solubility in water. Calcium fluoride is primarily used in the production of hydrofluoric acid, as a flux in metallurgy, and in the manufacturing of optical components due to its transparency across a wide spectrum. TSS supplies this essential chemical in various grades.

Flux in Metallurgy
Calcium fluoride is widely employed as a fluxing agent in the steel and aluminium industries. It lowers the melting point of slag, increasing fluidity and making it easier to remove impurities.
Hydrofluoric Acid Production
This compound is the primary industrial source for producing hydrofluoric acid (HF). Reacting calcium fluoride with sulfuric acid yields HF, a crucial chemical for numerous industrial processes.
Optical Materials
Due to its excellent transparency across ultraviolet, visible, and near-infrared wavelengths, calcium fluoride is used in manufacturing lenses, windows, and prisms for optical instruments.
Ceramics and Enamels
It is incorporated into the production of certain ceramics and enamels, acting as a flux and contributing to opacity and glaze properties.
