ABSTRACT:
Provided are an amorphous coke for a special carbon material characterized in that it is an amorphous coke obtained by blending a coal tar base heavy oil and/or a petroleum base heavy oil with a resin and subjecting the mixture to thermal decomposition polycondensation; it has a larger thermal expansion coefficient than that of a coke obtained from a heavy oil alone; and a molded article of the coke is shrunk by 0.3% or more in terms of a volume change rate before and after the treatment when it is subjected to graphitizing treatment, and a production process of an amorphous coke for a special carbon material characterized in that in subjecting a coal tar base heavy oil or a petroleum base heavy oil to thermal decomposition polycondensation, the raw material is blended with a resin to modify a coke crystal structure.
