Magnesium silicide Mg2Si is an inorganic compound consisting of magnesium and silicon. As a powder magnesium silicide is dark blue or slightly purple in color. Silicon dioxide SiO2 found in sand and glass when heated with magnesium forms magnesium oxide and if an excess of magnesium is used magnesium silicide is formed. The first product in this reaction is silicon which then reacts further with magnesium to produce Mg2Si.
