WebJan 4, 2024 · In the present work, we calculate the basic structural parameters of graphite after various treatments. The crystalline structure of structure is most commonly characterized by the interplane distance d00l, the dimensions of the structural components L a and L c , and the degree of order. WebThe degree of graphitization and the crystallinity parameter were characterized by X-ray diffraction (XRD) and Raman spectroscopy. The surface chemical composition of synthetic graphite materials was characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). download jdk 8 version
