Abstract
| - We present in this report a new type of particles with micrometer-order sizes, which we called giant graphiticballs (GG balls). The GG balls are produced by CO2 laser ablation of graphite together with single-wallcarbon nanohorns. They have graphitic structures whose layers tend to align parallel with the GG-ball surfaces,resulting in polygonal-like arrangements. Comparing the GG-ball structure with that of the previously reportedpolygonal graphite-particles, the growth mechanism of the GG ball is discussed briefly.
