Calcium Silicide

 
Calcium Silicide is an inorganic compound (a silicide of Calcium). It is whitish, dark grey to black solid matter with a melting point of 1033°C. It is insoluble in water, but may decompose when subjected to moisture, evolving Hydrogen and producing Calcium Hydroxide. It usually contains Iron & aluminium as contaminants, and low amounts of carbon & sulfur. Calcium Silicide is used for manufacture of special metal alloys mostly for removing phosphorous and as a deoxidizer.
