| Abstract: | Carbon nanospheres were prepared via CaC2-CHCl3 system,and the phase,morphology and microstructure of the pyrolytic products were detected by X-ray diffraction(XRD) and scanning electron microscope(SEM).Gibbs free energies and reaction thermodynamics of the system were theoretically calculated.Combining with experimental analysis,the mechanism for intermediate state carbon formation of carbon nanospheres by inorganic chemical reaction technology was studied.The results show that the pyrolytic products of Ca... |
