ABSTRACT:
Carbonates, oxides, carbides or fluorides of alkaline earth metals are added to coal tar pitches before coking. After the coking, which is preferably carried out by the delayed coking process, this produces coal tar pitch cokes or coal tar pitch needle cokes which have no irreversible expansion or a strongly reduced irreversible expansion upon heating in the temperature range of 1400.degree. to 2000.degree. C.
