Cadmium fluoride Usage And Synthesis
Chemical PropertiesWhite powder
Physical propertiesColorless cubic crystal; density 6.33 g/cm3; melts at 1,110°C; vaporizes at 1,748°C; vapor pressure 5 torr at 1,231°C; moderately soluble in water, 4.35 g/100mL at 25°C; soluble in hydrofluoric and other mineral acids; practically insoluble in alcohol and liquid ammonia.
UsesManufacture of phosphors, glass; in nuclear reactor controls.
DefinitionAvailable as pure crystals, 99.89%, d 6.6, mp approx- imately 1110C, soluble in water and acids, insoluble in alkalies.
PreparationCadmium 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.
Safety ProfileConfirmed 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.
Purification MethodsCrystallise 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.]
