A metathesis reaction route to obtain fine Mg₂Si particles.

We have developed a novel synthetic route for the production of fine Mg2Si particles (<1 μm) using NaSi, MgCl2, and Na. Mg2Si was suggested to be formed by a solid-state metathesis reaction, in which MgCl2 reacts with Na to form Mg and NaCl, and then Mg reacts with NaSi.
