Calcium Silicide

Calcium silicide may refer to Calcium monosilicide, CaSi and Calcium disilicide, CaSi2

Calcium monosilicide

Calcium monosilicide (CaSi) is an inorganic compound, a silicide of calcium. It can be prepared by reacting elemental calcium and silicon at temperatures above 1000 °C.[3] It is a Zintl phase, where silicon has oxidation state -2 and covalence 2.

Calcium disilicide

Calcium disilicide (CaSi2) is an inorganic compound, a silicide of calcium. It is a whitish or dark grey to black solid matter with melting point 1033 °C. It is insoluble in water, but may decompose when subjected to moisture, evolving hydrogen and producing calcium hydroxide. It decomposes in hot water, and is flammable and may ignite spontaneously in air.
