<P>PROBLEM TO BE SOLVED: To provide mesocarbon microspheres for carbon materials stably manufacturing high density and high hardness carbon products such as a high density and high hardness graphite block as a final product. <P>SOLUTION: The mesocarbon microspheres for high density and high hardness carbon materials have a particle diameter at the cumulative mass 30% of ≤8 μm, a particle diameter at the cumulative mass 50% of 9-14 μm, and a particle diameter at the cumulative mass 70% of ≥16 μm. Preferably, the ratio of the particle diameter at the cumulative mass 70% to the particle diameter at the cumulative mass 30% is 2.0-3.0. <P>COPYRIGHT: (C)2007,JPO&INPIT |
