    摘要: Solid carbon material having extremely high flexural strength can be produced by introducing a sufficient amount of functional group to satisfy the undernoted general equation into a pitch having a H/C atomic ratio of 0.8 at most, thereby obtaining precursory carbon material; shaping said precursory carbon material into a desired article without using any binding material; and carbonizing or further graphitizing said article; wherein the general equation is ##EQU1## where, H/C is the hydrogen-to-carbon atomic ratio of the pitch, R is a numeral ranging from 0.2 to 0.3, and f is the percent by weight of at least one of oxygen, sulfur and halogen contained in the total functional groups introduced into the precursory carbon material on the basis of the weight thereof.

    摘要: Crystalloidal pitch is obtained by subjecting solid pitch particles measuring not more than 5 mm in cross-sectional equivalent diameter to a treatment to prevent cohesion and subsequently bringing the cohesion-proof solid pitch particles into contact with a non-oxidative gas at temperatures of from 350.degree. C to 550.degree. C while maintaining a gas flow rate sufficient to provide a suspension wherein the gas constitutes at least 30% by volume. The crystalloid pitch is useful as a precursor for various carbon products.
