摘要：

Nanostructured fayalite (alpha-Fe2SiO4) with a large volume fraction of interfaces is synthesized for the first time via single-step mechanosynthesis, starting from a 2 alpha-Fe2O3 + 2Fe + 3SiO(2) mixture. The nonequilibrium state of the as-prepared silicate is characterized by the presence of deformed polyhedra in the interface/surface regions of nanoparticles.
