The graphitization of amorphous carbon is an attractive process for enhancing the properties of carbon materials used in electrical and metallurgical applications. This study investigates the graphitization kinetics of tube-shaped samples fabricated from a mixture of coke and molasses. Samples were subjected to isothermal heat treatments for one hour at temperatures ranging from 1600 °C to 2500 °C. The structural evolution was quantitatively analyzed using X-ray diffraction (XRD), measuring the interplanar spacing (d₀₀₂), crystallite size (Ls), and degree of graphitization. The results demonstrate a strong positive correlation between process temperature and crystallinity, with the graphitization degree increasing from 17% at 1600 °C to 58% at 2500 °C. Concurrently, the d₀₀₂spacing decreased from 0.344 nm to 0.33 nm, and the crystallite size Ls grew from 5 nm to 45 nm. However, the inability to achieve full graphitization even at the highest temperature confirms the time-dependent, kinetic nature of the process. The findings align with established models and confirm that the cokemolasses system can be effectively graphitized to produce materials with potential for industrial use, though optimization of both time and temperature parameters is essential for complete crystallization.
