The experimental evidence has shown that the polygonal Co particles are the final form. We found that Co formed nanocrystallites of 2-5 nm in diameter in the surface coating layer of the Mg_2SiO_4 crystalline stems and then aggregate into large clusters. These clusters further grow and recrystallize into polygonal single crystals. Instead of the single crystals, it is the polycrystalline clusters that played the most important role in Mg_2SiO_4 growth.c.
