Calcium silicide is used for deoxidation mostly used for scientific research. 

It is designed to increase the amount of heat conductive material to prevent 

the formation of oxidization of iron.. It is used for deoxidation of steelmaking a

nd additive of special steel.


Calcium silicate can react with water to form combustible hydrogen silicide gas. 

Therefore, after calcium silicate fire breaks out, it can’t be extinguished with water 

or carbon dioxide fire extinguisher, sand or dry powder fire extinguisher can be used.
