Abstract
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.degree. C. under a pressure load of 10 kgf/cm.sup.2. 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.
