摘要：

Polyhedral graphite (PG) particles have been synthesized by CO2 laser vaporization of graphite in high-pressure Ar gas (8 x 10(5) 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.
