Calciumsilicide

Calciumsilicide, also known as calcium - silicon, are a group of intermetallic compounds of calcium and silicon.

Producing Calciumsiliciden can firstly by the melting of calcium carbide ( CaC 2 ) and silicon dioxide (SiO2), are produced on the other by the reduction of silicon dioxide, calcium oxide or calcium carbide with carbon in an electric furnace.

Like many other silicides have also Calciumsilicide a good electrical conductivity. However, this is highly dependent on the modification, as for example Dicalciumsilicid ( Ca2Si ) a semiconductor.

Are used Calciumsilicide example, in metal processing. There they are partly due to its strong reducing properties as a deoxidizer for steel used.
