  • Calcium silicide (CaSi2), also called calcium disilicide, is an inorganic compound, a silicide of calcium.
  • It is a whitish or dark grey to black solid matter with melting point between 700-935C.
  • Calcium Silicide is insoluble in water, but may decompose when subjected to moisture, evolving hydrogen and producing calcium hydroxide.


  • Calcium silicide is used for manufacture of special metal alloys, eg. for removing phosphorus and as a deoxidizer.
  • In pyrotechnics, it is used as fuel to make special mixtures, eg. for production of smokes, in flash compositions, and in percussion caps.
  • Calcium silicide is used in the manufacture of certain initiatory, pyrotechnic and smoke compositions.


  • Calcium silicide has been found to be extremely corrosive to all metals including the refractory metals. It has been successfully contained in boron nitride for 36 hours.
  • Ceramics and cermets now appear to be the only potential long duration containment materials for calcium silicide.
