초록

High-purity and super-hard nano-polycrystalline diamond has been successfully synthesized by direct conversion from high-purity graphite under static pressures above 15 GPa and temperatures above . This paper describes research findings on the formation mechanism of nano-structure and on the contributing factor leading to high hardness.
