Abstract
Disclosed are an iron-carbon composite in which 10 to 90% of the internal space of a nanoflake carbon tube or a nested multi-walled carbon nanotube is filled with iron carbide or iron; a carbonaceous material containing such iron-carbon composites; and a process for preparing the same. The iron-carbon composite is useful for electron emitting materials and other applications.
