- Abstract
Super-fine mesophase powder (SFMP) was prepared from a coal tar pitch accompanying mesocarbon microbeads (MCMB) and then was manufactured into high density and isotropic carbon (HDIC) bulks. The influence of β-resin content in SFMP precursors and sintering conditions has been studied on the performance of derived HDIC. It has found that, to obtain HDIC with excellent mechanical performance, suitable β-resin content in SFMP and sintering rate are required. In the sintering range of 743K-1273K, higher temperature facilitate the formation of compact HDIC with high flexural strength. Volume shrinkage during sintering can be adopted to valuate approximately the mechanical performance.
