Sr2SiO4 flower-like nanostructures grown by thermal oxidation of SrSi2 with Ga droplets

Sr2SiO4 flower-like nanostructures were grown by thermal oxidation of SrSi2 powders with Ga droplets. The morphology and structure of the Sr2SiO4 flower-like nanostructures were investigated using transmission electron microscopy. The leaves of the Sr2SiO4 flower-like nanostructures became narrow towards the tips. Sr, Si and O were homogeneously concentrated on each leaf. In addition, the formation mechanism of the Sr2SiO4 flower-like nanostructures was discussed.
