ABSTRACT:
The process produces carbon bodies from coal tar pitch coke which have a strongly reduced or no irreversible thermal expansion in the temperature range of 1400.degree. to 2000.degree. C. Before shaping, a sulphonate, carboxylate or phenolate of an alkaline earth metal which is at least partially soluble in the binder is added to the mixing constituents which consist of particulate coke and a cokable binder as raw materials. After the mixing, shaping and firing, bodies are obtained which have only slight puffing upon graphitization.
