Cadmium fluoride Chemical Properties,Usage,Production

  • Chemical Properties White powder
  • Physical properties Colorless 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.
  • Uses Manufacture of phosphors, glass; in nuclear reactor controls.
  • Definition Available as pure crystals, 99.89%, d 6.6, mp approx- imately 1110C, soluble in water and acids, insoluble in alkalies.
  • Preparation 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.
  • Safety Profile 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.
  • Purification Methods 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.]
