Calcium Fluoride Crystal Description


Calcium Fluoride Crystal is a transparent material that consists of calcium and fluoride ions arranged in a crystal lattice structure. It has the chemical formula CaF2 and is commonly found in nature as a mineral called fluorite. Calcium Fluoride Crystal has a cubic crystal structure and is often used as a lens material in optical devices due to its low refractive index and high transmission in the ultraviolet, visible, and infrared regions of the electromagnetic spectrum. It is also used as a source of fluoride ions in various applications, such as in toothpaste and water fluoridation for dental health.
