    Abstract
  • Using a two-stage light gas gun and shock recovery technique, a series of experiments up to 40-65 GPa were carried out on the nitrogen-rich material of precursor g-C3N4. The powder X-ray diffractions (XRD) of recovered samples showed that the precursor g-C3N4 was stable under 51 GPa pressure, while only a new crystalline phase -C3N4 was obtained during 51-65 GPa pressure. The results confirm that -C3N4 can be synthesized directly from precursor g-C3N4. This paper is significant for the study of synthesizing pure superhard carbon nitrides.
