Applications

Calcium fluoride is the commercially important source for fluoride compounds as well as hydrogen fluoride. It is transparent from ultraviolet to infrared region. It is used in spectroscopy, thermal imaging systems and excimer lasers; it is also used in the manufacturing of optical components including windows, prisms and lenses. In addition, it is also used in aluminum-metallurgy, brake lining manufacturing industries, and in tooth enamel.

Notes

Hygroscopic. On contact with strong acids, it produces hydrogen fluoride.
