Cadmium fluoride (CdF2) is a mostly water-insoluble source of cadmium used in oxygen-sensitive applications, such as the production of metallic alloys. In extremely low concentrations (ppm), this and other fluoride compounds are used in limited medical treatment protocols. Fluoride compounds also have significant uses in synthetic organic chemistry. The standard enthalpy has been found to be −167.39 kcal. mole−1 and the Gibbs energy of formation has been found to be −155.4 kcal. mole−1, and the heat of sublimation was determined to be 76 kcal. mole−1.
