摘要

PCT No. PCT/JP92/00800 Sec. 371 Date Apr. 2, 1993 Sec. 102(e) Date Apr. 2, 1993 PCT Filed Jun. 23, 1992 PCT Pub. No. WO93/02988 PCT Pub. Date Feb. 18, 1993.A sintered product based on mesocarbon microbeads is prepared by pressure-molding mesocarbon microbeads (MCMB) having an MSP (maximum solubility percent) value of 30 to 38% by volume whereby a body is formed, and sintering the body, wherein MSP represents the percentage volume reduction (volume %) determined by heating a given amount of an MCMB to 350 DEG C. under a pressure load of 10 kgf/cm2. The quality of a molded MCMB sintered product can be controlled by determining the percentage volume reduction (MSP) of an MCMB by heating it under a given pressure load in a predetermined space using the MSP value so found as an indicator.
