From a structural viewpoint, the term coke characterizes the state of graphitizable carbon before the beginning of graphitization."},"links":[{"term":"carbonization","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/C00840"},{"term":"graphitizable carbon","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/G02690"},{"term":"graphitization","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/G02691"},{"term":"non-graphitic carbon","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/N04193"},{"term":"pyrolysis","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/P04961"}],"sources":["PAC, 1995, 67, 473.
