摘要：

We present a study of the heat treatment of carbon soot generated by an electric are using graphite electrodes and run in a low inert gas helium pressure. This carbon soot has been incompletely characterized; primary results indicate properties distinct from other carbons. Heat treatments from 500-2400 degrees C were applied. At 1700 degrees C a glassy carbon material is obtained, but above 2000 degrees C the generation of multilayer closed graphitic particles was observed. The size of the closed shell graphitic particles is very small (3-10 nm). These results suggest that a macroscopic quantity of fullerene-related particles, as well as short nanotubes, may be obtained by a simple thermal treatment of fullerene black.
