Production of nanosized graphite powders from natural graphite by detonation

---

Abstract.
A detonation method for preparing nanosized graphite powders from natural graphite is
described. The process initiated by a detonator in an explosion vessel features quick release
of energy, decomposition of HNO3 graphite intercalation compounds and the smashing
action due to the detonation. The products were soot-like deposits on the inner walls of
the vessel, and were studied by XRD, SEM, TEM, BET, energy dispersive X-ray spectroscopy,
and Raman spectroscopy. The results show that the as-made graphite powders have a perfect
sheet-like structure, and vary in the two-dimensional plane at the micron scale and in
thickness at the nanoscale. The specific surface area of the nanosized graphite is six times
higher than that of the raw graphite. This technique may offer a low-cost, energy saving
and efficient approach to the preparation of nanosized graphite powders.
