Journal of Nanoparticle Research Synthesis of silicon

2017. 6. 10.  The process of surface oxidation for silicon nanoparticles produced using ball milling occurs mainly during the milling process when dangling bonds of the exposed surface silicon react with oxygen to form combinations of Si 0 to Si 4 bonding. Any further growth of the surface oxide layer from atmospheric oxidation will be minimal.
