Cadmium 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.Definition
Available as pure crystals, 99.89%, d 6.6, mp approx- imately 1110C, soluble in water and acids, insoluble in alkalies.synthetische
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 → CdF2
Cd + 2HF → CdF2 + H2
CdO + 2HF → CdF2 + H2O
It 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 + CO2
It also may be prepared by mixing cadmium chloride and ammonium fluoride solutions, followed by crystallization.
Sicherheitsprofil
Confirmed human carcinogen. Poison by subcutaneous route. Violent reaction with K. When heated to decomposition it emits very toxic fumes of Cd and F-. See also FLUORIDES and CADMIUM COMPOUNDS.l?uterung methode
Crystallise it by dissolving it in hot water (25mL/g at room temperature) at 60o, filtering, then cooling. [Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 243 1963.]Cadmiumfluorid Upstream-Materialien And Downstream Produkte
