Application

Calcium fluoride, commonly known as fluorite or fluorspar, is a versatile and colorless crystalline substance with a range of industrial applications. Its low solubility in water and transparency make it ideal for detecting gamma rays and charged particles, albeit with a limitation in gamma-ray spectrometry at higher energies due to its low atomic number. This property also makes it an effective detector for beta particles with minimal backscattering. Additionally, calcium fluoride serves as a crucial material in the production of hydrofluoric acid and in the etching of glass. The compound's high resistance to thermal and mechanical shock allows it to be fabricated into various detector geometries. It is not hygroscopic, making it suitable for a variety of vacuum applications and direct contact with radioactive samples. In the steel industry, it is used as a flux to increase slag fluidity, while in the chemical sector, it is a source for fluorine and its compounds. Furthermore, calcium fluoride is utilized in the optical industry for UV-ray transmission and in the production of enamels, ceramics, and white cement. Its application extends to fluoridating drinking water, and the pure form plays a role as a catalyst in dehydration and dehydrogenation processes.
