Term: coke
https://doi.org/10.1351/goldbook.C01142

Definition:
A solid high in content of the element carbon and structurally in the non-graphitic state. It is produced by pyrolysis of organic material which has passed, at least in part, through a liquid or liquid-crystalline state during the carbonization process. Coke can contain mineral matter.

Note: As some parts, at least, of the @C00840@ product have passed through a liquid or liquid-crystalline state, the resulting @N04193@ is of the graphitizable variety. From a structural viewpoint, the term coke characterizes the state of @G02690@ before the beginning of @G02691@.
