The method of obtaining magnesium silicide

It can be produced by heating silicon dioxide, SiO2, found in sand, with excess magnesium. The process first forms silicon metal and magnesium oxide, and, if an excess of SiO2 is used, then elemental silicon is formed: 2 Mg + SiO2 → 2 MgO + SiIf an excess of Mg is present, Mg2Si is formed from the reaction of the remaining magnesium with the s
