Popis: In this study, we aimed to estimate the weight fraction of crystalline phases in a cathode deposition formed by DC arc-discharge between graphite electrodes in water via the XRD method and CARBON XS program based on Shi model, which takes into account disorder and stacking faults in a graphite structure. The structural computation of graphitic carbon materials for comparison was done by using CARBON XS according to Shi model. From the study, we observed that the total weight fraction of 2H hexagonal and 3R rhombohedral ordered structures of graphitic carbon decreases from 77.69% to 48.98%, whereas the weight fraction of random shift and stacking faults increases from 22.31% to 51.02% as compared to these parameters belonging to pure graphite structure during the arc-discharge process.
