Characteristic
Magnesium silicide, Mg2Si, is an inorganic compound consisting of magnesium and silicon.Mg2Si is the only stable compound of mg-si binary system. It has the characteristics of high melting point, high hardness and high elastic modulus. It is a kind of n-type semiconductor material with narrow band gap.
Chemical formula:Mg2Si
Molar mass:76.695 g·mol−1
Appearance:Gray cubic crystals
Density:1.99 g/cm3
Melting point:1102 °C (2,016 °F; 1,375 K)
Solubility in water: reacts
Crystal structure:Cubic, cF12
Application
Magnesium silicide is commonly used in the production of aluminum alloys. This alloy contains about 1.5% magnesium silicide, which has the characteristics of aging and hardening, forming the guinier-preston region and very uniform precipitation, which can improve the strength of the alloy.
