Graphitic carbon nitride (g-C3N4) is prepared by pyrolysis of melamine. At room temperature, the structure change of the g-C3N4 is investigdted by in situ high pressure angle-dispersive X-ray diffraction with a synchrotron radiation source, which is in a diamond-anvil cell. The results show that structural phase transition occurred in g-C3N4 within 16.57 GPa pressure range. The crystal structure changes from graphitic to triclinic structure at 6.6 GPa. The isothermal equation of the state of C3N4 is fitted using the Birch-Murnagha equation of state.
