Abstract: PURPOSE:To obtain material powder for self-sinterable high-strength, high-density carbonaceous materials low in the deterioration with time of sinterability by oxidation of self-sinterable carbonaceous material powder to suppress its oxidation rate to low levels during its preservation. CONSTITUTION:Coal tar pitch is heated to form fine mesophase spheres, which are then taken out from the heat-treated pitch by solvent extraction to produce self-sinterable carbonaceous material powder. Subsequently, to regulate the sinterability of this powder to a level higher than the aimed sinterability, the powder is calcinated at 200-450 deg.C or so, and then either held at 50-300 deg.C in air for a specified time or oxidized, under agitation, in a mixer capable of heating operation such as Henschel mixer. Although the sinterability of the material powder is declined due to this oxidation, this sinterability has been regulated to a level higher than the aimed sinterability; therefore, the objective material power having the aimed sinterability and low in the oxidation rate during its preservation can be obtained.
