摘要：

Graphitization of coal-derived asphaltenes at 1600-1800 degree C under a pressure of 1 GPa was examined. The interlayer spacing, d//0//0//2, decreased with increasing heat treatament temperature, down to 0. 336-0. 337 nm at 1800 degree C, which is almost the same as that of graphite. The crystallite thickness in the c-direction, Lc//0//0//2, increased significantly with decreasing d//0//0//2.
