Graphite d-spacing
WebThe XRD patterns of graphite and GOs showed that the graphite powder presents a very intense and narrow peak at 26.6°, which is attributed to the graphite spacing (0 0 2) of graphite plane (Figure 3d) . After the oxidation of graphite by three different methods, the (0 0 2) peak of graphite disappears and another strong peak appears at about 8 ...

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 WebAppearance of reflex at 2θ vale between 10° and 10.5°with an interlattice spacing (d-spacing) close to 0.76 nm in case of GO is ascribed to the diffraction from a typical C …

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.
