Introduction. Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica is found commonly in the crystalline state and rarely in an amorphous state. It is composed of one atom of silicon and two atoms of oxygen resulting in the chemical formula SiO2.

Although the reaction of Mg and silica is thermodynamically highly favorable, direct reaction using commercial Mg powder by mechanical milling at room temperature is difficult. However, by adding of 5 wt % Mg 2 Si, silica nanoparticles can be reduced into Si nanoparticles using commercial Mg as the reductant by mechanical milling at 250 rpm in 5 h.
