Abstract
The coal tar pitch and phenol resins are used as binders in artificial graphite manufacture, but there are differences in the initial carbon compound structure. According to the carbonization temperature, it can be expected that there are differences in thermal decomposition behavior, microstructure, and crystallinity change. These properties of the coal tar pitch and phenol resins were compared to each other. As the carbonization temperature of coal tar pitch and phenol resin increases, crystallinity tends to increase. The coal tar pitch went through the carbonization process through the liquid, and it was confirmed that the crystallinity changed rapidly in the temperature range of 500 and 600 ℃, where the microstructure changed quickly. These results confirmed the close correlation between microstructure and crystallinity.
