CALCIUM SULFIDE Usage And Synthesis
  • Chemical PropertiesCALCIUM SULFIDE is OFF-WHITE POWDER
  • Physical propertiesCalcium sulfide is slightly soluble in water but insoluble in alcohol. It reacts with acids, producing hydrogen sulfide gas. Calcium sulfide is pale yellow to light gray with a bitter taste. It is hygroscopic, producing an odor of H2S in moist air.
  • OccurrenceCalcium sulfide occurs in nature as the mineral oldhamite. It has several applications. The ‘luminous’ calcium sulfide is used in phosphors, luminous paints and varnishes. Calcium sulfide also is used as an additive to lubri cants; and as a flotation agent in ore extraction.
  • UsesCALCIUM SULFIDE is  used in electron emitters. Luminous CaS used for making luminous paints or varnishes.
  • PreparationCalcium sulfide can be prepared by the direct reaction of the elements, calcined in an inert atmosphere, at a 1:1.05 molecular ratio:
    Ca+S+heat→CaS
    This white material crystallizes in a cubic structurelike rock salt and the bonding is highly ion
