Abstract

The present invention concerns a process for producing carbon nanotubes or other carbon nanostructures, e.g. cones. The process comprising evaporating/decomposing a carbon containing material in a voluminous thermal plasma generated by rotating an electric arc using an externally applied magnetic field, and condensing said evaporated/decomposed carbon containing material on surfaces or on particles in a gas flow. A reactor for performing the process is also described.
