개요
Cadmium fluoride is a water-insoluble chemical compound of cadmium used in oxygen-sensitive applications, such as the production of metallic alloys. Cadmium is a transition metal and chemical element with the symbol Cd and atomic number 48. It is found naturally in the earth's crust, though rarely on it's own. (L6, L467)

약리 정보
Metabolism/Metabolites
Cadmium is absorbed from oral, inhalation, and dermal routes. Cadmium initially binds to metallothionein and albumin and is transported mainly to the kidney and liver. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Cadmium is not known to undergo any direct metabolic conversion and is excreted unchanged, mainly in the urine. (L6)

응용 분야
용도Cadmium fluoride is used in phosphors, glass and nuclear reactor controls. It is also used in high-temperature lubricants and to start crystals for lasers. It is used in oxygen-sensitive applications such as the production of metallic alloys and it is also used in limited medical treatment protocols. In addition, it can be used in synthetic organic chemistry.
제조 방법
Cadmium fluoride is prepared by the reaction of gaseous fluorine or hydrogen fluoride with cadmium metal or its salt, such as chloride, oxide or sulfide:Cd + F2 → CdF2Cd + 2HF → CdF2 + H2CdO + 2HF → CdF2 + H2OIt also may be obtained by dissolving cadmium carbonate in 40% hydrofluoric acid solution, evaporating the solution and drying in vacuum at 150°C:CdCO3 + 2HF → CdF2 + H2O + CO2It also may be prepared by mixing cadmium chloride and ammonium fluoride solutions, followed by crystallization.
