PURPOSE:To obtain a mesocarbon microbead baked or graphitized with a good reproducibility at a low cost. CONSTITUTION:A mesocarbon microbead is baked to 120 deg.C) in the air and graphitized in an inert or nonoxidizing atmosphere at a temp. rise rate of 10 deg.C/hr to 1,000 deg.C, if necessary to 3,000 deg.C. |
