WebWest Virginia University The compression behavior of graphite was investigated by synchrotron XRD (Fig. 1). At pressures up to ~19 GPa, the (002) peak of H-graphite shifts more rapidly toward smaller d-spacing than the other H-graphite peaks, confirming that the compressibility of H-graphite is highly anisotropic with the c-axis … See more The XRD results are consistent with Raman spectra taken of graphite collected under compression (Fig. 5). From the spectra, we can clearly see that starting at ~20 GPa, the G band … See more As compared to the bulk HOPG starting material, the wide peak shape of the pressure-quenched H-graphite suggests that the microstructure of H-graphite in the quenched samples is distinct from the starting material, as … See more The equations of state of M-carbon and H-graphite are determined by fitting the pressure-volume data sets to a second-order Birch-Murnaghan EOS41,42, as shown in Fig. 2c.
