Calcium fluoride

Description:
Calcium fluoride (CaF₂) is an inorganic compound characterized by its crystalline structure and high stability. It appears as a colorless or white solid and is commonly found in nature as the mineral fluorite. Calcium fluoride is notable for its low solubility in water, making it relatively inert in aqueous environments. It has a melting point of approximately 1,418 °C and a boiling point of around 2,533 °C, indicating its thermal stability. The compound exhibits a cubic crystal system and is often used in various applications, including optics, where it serves as a lens material due to its transparency to ultraviolet light. Additionally, calcium fluoride is utilized in the production of aluminum, as a flux in metallurgy, and in the manufacture of certain types of glass. It is also important in the field of dental health, as fluoride ions can help in the prevention of dental caries. While generally considered safe, exposure to high concentrations of fluoride can pose health risks, necessitating appropriate handling and safety measures.

    Calcium fluoride

    CAS:
    <p>Calcium fluoride crystals are the mineral form of calcium fluoride, which is a high-resistance ionic conductor. Calcium fluoride has been used for many purposes, such as in the production of semiconductors and lasers. Calcium fluoride is also used as a radiation shield and in the production of hydrogen fluoride, which is an important chemical reagent. The crystal structure of calcium fluoride has been determined using x-ray crystallography and electron diffraction studies. This mineral has a hexagonal crystal system (space group P6 3 /mmc) with lattice constants a = 5.9 Å and c = 6.3 Å, where c equals the length of one side of an equilateral triangle that fits within the unit cell. The space group indicates that each unit cell contains twelve atoms: six Ca2+ and six F-. The unit cell dimensions are given by a = b = 1/2 × 10−8 m and c = 2 × 10−7 m. These</p>
