What is a Calcium Fluoride (CaF₂)?

Calcium fluoride (chemical formula: CaF₂) is an inorganic compound composed of calcium (Ca) and fluoride ions (F⁻). It is typically found as colorless or transparent crystals and is highly stable, being insoluble in water. Calcium fluoride has a wide range of industrial applications. It is primarily used in the production of fluorocarbons and as an additive in glass manufacturing. In glassmaking, calcium fluoride helps lower the melting temperature of the glass and improves its transparency. Additionally, calcium fluoride is used in optical devices, including lenses and windows that operate in the ultraviolet (UV) and infrared (IR) regions.

In the pharmaceutical field, calcium fluoride is used as a calcium source. Calcium is essential for bone and dental health, and calcium fluoride is sometimes used as a supplement to support these functions. Regarding safety, calcium fluoride is generally safe to handle, but it can pose health risks if ingested in large quantities. Proper precautions should be taken to avoid dust exposure to the eyes or inhalation, which can cause irritation or other health issues.
