Graphitization carbon
WebJul 1, 2024 · Phenolic resin was prepared with a boron oxide additive to catalyze the graphitization process. Boron oxide powder proved to be effective in inducing a sizable degree of graphitization (70%) at 1650 °C. This process took place at temperatures far below those at which such phenomena normally occur. The graphitized specimens were … WebIn this study, the influence of the addition of carbon nanotubes (CNTs) and carbon black (CB) on the graphitization temperature and microstructure of coal tar pitch (CTP) are investigated. X-ray diffraction patterns of carbon residues indicate that minimum interlayer spacing (d 002) values are obtained at 2000 °C for CTP/CNT. Moreover, the ...
