PURPOSE:To obtain a special carbonaceous material having a high density and processing characteristics by calcining the molded product of a mixture obtained by adding a carbonaceous powder satisfied with a specific condition originated from C-H when coke is kneaded with a binder. CONSTITUTION:A carbonaceous raw material is thermally treated to produce carbonaceous material powder having a volatile content of 3-30wt.%, an average particle size of 15-20mum and a toluene soluble content of 1-30wt.%. The product satisfied with one or more of eight conditions originated from the C-H in IR absorbance spectrum is selected from the thermal products. As the conditions, a ratio between the peak of an IR absorption spectrum originated from C-H at a place near to 2913cm<-1> based on 2935cm<-1> and 2860cm<-1> and the peak of an IR absorption spectrum originated from C=C at a place near to 1600cm- based on 1665cm<-1> and 1540cm<-1> is set to <=0.05. The changing rate from the carbonaceous raw material to a thermal treatment product in the peak ratio is set to <=0.07 as the other condition. The carbonaceous material powder is added when coke and a binder are kneaded.

That is, if the heat treatment proceeds too much, the amount of hydrogen in the carbonaceous powder decreases, the sinterability of the carbonaceous powder is lost, and the characteristics of the carbon material produced deteriorate. Those above the range are preferable. That is, the sinterability improves as the amount of aromatic hydrogen increases, and further as the amount of aliphatic hydrogen increases. Furthermore, the aromatic hydrogen or the aliphatic hydrogen in the carbonaceous powder is decomposed during firing to generate an aliphatic gas such as hydrogen gas or methane or ethane, which causes polycondensation to form a benzene ring. The degree of condensation increases and the hexagonal net surface develops.
During the firing, the carbon material has a large shrinkage, is likely to be highly dense, and improves the electrical discharge machining characteristics.

が好ましく、最も好ましくは１００℃以上である。Since these compounds are molded after crushing, if the solvent remains during crushing, it is difficult to crush them. Therefore, it is preferable that the compounds volatilize during the crushing and hardly remain. In the conventional method, since the mating is carried out at 300 ° C. or lower, those which volatilize at 300 ° C. or lower are preferable, the boiling point of the solvent is preferably 300 ° C. or lower, more preferably 280 ° C. or lower, and most preferably Is 250 ° C. or lower. If the boiling point of the solvent is too low, the flash point is low, which is dangerous. Therefore, the boiling point of the solvent is preferably 50 ° C. or higher, more preferably 80 ° C. or higher, and most preferably 100 ° C. or higher.
