PURPOSE:To obtain the titled molded body excellent in strength, dimensional stability and low electrical resistivity by distilling the more volatile fraction of distillate contained in the tar fraction contg. the mesophase pitch precursor which is suspended with the specified material, carbonizing or graphitizing it after molding. CONSTITUTION:After 5-1,000pts.wt. one or >=2 kinds of material selected among graphitic carbon, carbonaceous carbon, an inorganic compd. and metal (compd.) are suspended into 100pts.wt. tar fraction contg. a mesophase pitch precursor and an inert gas is blown thereinto to distill the more volatile fraction of distillate, it is heated at 350-500 deg.C to obtain the carbonaceous precursor wherein the mesophase-contg. pitch contg. 5-90wt% quinoline soluble content is formed on the surface of material. Then the precursor is molded at the temp. <=400 deg.C from the softening temp. and above the S.P. of pitch and the obtained green molded body contg. mesophase pitch-contg. pitch is carbonized or graphitized in the temp.-rise velocity of 1-1,500 deg.C/hr in an inert atmosphere. |
