Nano size Si particles fabricatied by shock-induced decomposition reaction of SiO was studied by shock recovery experiments to 18~39 GPa using gun method. The particle size at 18 GPa is about 20 nm, whereas the size became rapidly larger as shock pressure increase, and reach to 50 nm at 34 GPa. The particles emerged nano Si with spherical shap and single domain.
