Synthesis Of Coal Nanoparticles By Ball Milling
Large-scale synthesis of ultrafine Si nanoparticles by ...
Si nanoparticles have been synthesized by ball-milling of graphite and SiO 2 powders. The solid-phase reaction, C (graphite)+SiO 2 →Si+CO 2, was found to be a novel technique for fabrication of ultrafine Si particles. The reduced Si in the powder assembled as nanoparticles with a wide range of diameters.
