A solid high in content of the element carbon and structurally in the non-graphitic state. It is produced by @P04961@ of organic material which has passed, at least in part, through a liquid or liquid-crystalline state during the @C00840@ process. Coke can contain mineral matter.
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@.
