چکیده انگلیسی
Activated carbon was treated at 5.0 GPa up to 1600 ∘C and the structural evolution in the graphitization process was investigated. The graphitization temperature is reduced to 1200 ∘C at 5 GPa, as reflected by x-ray diffraction patterns. Honeycomb-like structures come into being in the high-pressure sintering temperature range of 1000–1100 ∘C and slice-like structures appear after graphitization. Raman frequency and half width drop drastically near the graphitization temperature, and the appearance of D and D′ lines indicates there are still some disorder structures in the graphitized activated carbon.
