Term: coal-derived pitch coke
https://doi.org/10.1351/goldbook.C01118

Definition:
The primary industrial solid carbonization product obtained from coal tar pitch mainly produced in chamber or delayed coking processes.

Note: Coal-derived @P04677@@C01142-1@, although it exhibits a pregraphitic microstructure, has often a lower graphitizability than @P04522@. Fractions of coal tar pitches (obtained by @E02301@ or @F02388@) may form @C01142-2@ with needle-like structures and have an improved graphitizability. The usually lower graphitizability compared to @P04522@ is due to an @I03034@ of @M03849@ growth because of chemical and physical differences of the cokes.
