Method for producing solid carbon material having high flexural strength |
| abstract |
ABSTRACT Solid carbon articles having high flexural strength and low porosity can be produced by introducing a suitable amount of oxygen, sulfur or halogen into a raw pitch material so as to satisfy the undernoted general equation, thereby obtaining a precursory carbon material containing therein functional groups; press-forming said precursory carbon material into a desired article; and subsequently carbonizing and graphitizing said shaped article; wherein said general equation is represented by where, H/C is a hydrogen-to-carbon atomic ratio of the raw pitch material, f is a variable weight percent of oxygen, sulfur or halogen introduced into the raw pitch material, and R is an almost constant numeral ranging from 0.2 to 0.3. |
