graphite powdered by ball milling

  • One Step Ball Milling Preparation of Nanoscale CL 20

    A one step method which involves exfoliating graphite materials (GIMs) off into graphene materials (GEMs) in aqueous suspension of CL 20 and forming CL 20/graphene materials (CL 20/GEMs) composites by using ball milling is presented. The conversion of mixtures to composite form was monitored by scanning electron microscopy (SEM) and powder X ray diffraction (XRD).

  • Ball milling the behavior of graphite as a function of

    The ball milling of graphite in the presence of a liquid leads to very thin, well crystallized and anisometric particles. In the presence of water, the graphite particles are covered by Fe 2 O 3 (maghemite) formed by the oxidation of the ferrous alloy coming from the milling tools. This composite presents interesting electrochemical properties.

  • Synthesis and characterization of graphite encapsulated

    Ball milling of Fe 2 O 3 powder without graphite was also tested. While reduction to metallic iron was again successful, the iron particles in direct contact led to mm scale iron fragments, shown in Supplementary Fig. 1. This demonstrates that ball milling alone is insufficient to produce nanoscale encapsulated particles.
