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.

b。实验中观察到的现象表明多面体的Co颗粒并不是一开始就形成的，而是首先在Mg_2SiO_4的枝干表面以2-5nm的纳米晶体聚集成较大的团簇，这些团簇再继续生长并在最后重结晶为多面体的形状。
