| Abstract: | Polyhedral graphite (PG) particles have been synthesized by CO2 laser vaporization of graphite in high-pressure Ar gas (8×105 Pa). Faceted PG particles, ranging in size from 110 to 500 nm, have a turbostratic structure. The yield of PG is more than
90%. This synthesis is based on the condensation of hot carbon species confined by an Ar-gas atmosphere.
