PROCESS FOR PREPARATION OF CARBON NANOTUBES FROM VEIN GRAPHITE

A catalyst free process for manufacturing carbon nanotubes by inducing an arc discharge from a carbon anode and a carbon cathode in an inert gas atmosphere contained in a closed vessel. The process is carried out at atmospheric pressure in the absence of external cooling mechanism for the carbon cat...
