Graphite d-spacing
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. The … See more In the present study, we explore the sluggishness of the phase transition from H-graphite to M-carbon at selected pressures using synchrotron XRD, Raman spectroscopy and … See more WebDec 27, 2016 · It was found that, at temperatures lower than the melting point of FLiNaK, the CCTE of the d (002) spacing of graphite decreases with an increase in the weight of the graphite sample because of FLiNaK infiltration. On the other hand, the CTE of bulk graphite increases after molten salt infiltration.
