Abstract: The invention has as an object proving a carbon nanomaterial fabrication method that can continuously mass-produce a high purity carbon a nanomaterial. The tube-shaped or fiber-shaped carbon nanomaterial having carbon as the main constituent is fabricated with a compound that includes carbon (raw material) and an additive that includes a metal by using a fluidized bed reactor.

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.
