Magnesium silicide, Mg2Si CAS 22831-39-6 used to build Mg-Si rectifiers

Product Introduction of  Magnesium silicide Mg2Si


Magnesium silicide, Mg2Si, is an inorganic compound consisting of magnesium and silicon


Syntheis of Magnesium silicide Mg2Si


It can be produced by heating silicon dioxide ,SiO2,found in sand , with excess magesium .


The process first forms silicon metal and magnasium oxide , and, if an excess of magnesium is used, the silicide is formed:

2 Mg + SiO2 → 2 MgO + Si


If an excess of Mg is present, Mg2Si is formed from the reaction of the remaining magnesium with the silicon:

2 Mg + Si → Mg2Si


These reactions proceed exothermically.

Application of Magnesium silicide Mg2Si
1. Magnesium silicide is used to create aluminium alloys of the 6000 series, containing up to approximately 1.5% Mg2Si.


2.An alloy of this group can be age-hardened to form Guinier-Preston zones and a very fine precipitate, both resulting in increased strength of the alloy


3. Used in semiconductor research.


4. Used to build Mg-Si rectifiers.
