METHOD AND APPARATUS FOR PRODUCING CARBON NANOTUBE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube by which a cathode deposit can stably be produced and electrodes need not be exchanged for each production of the cathode deposit. SOLUTION: An initial current exceeding a prescribed discharge current is made to flow prior to the flow of the prescribed discharge current and continuation of arc discharge in a step for carrying out the arc discharge in a method for producing a carbon nanotube comprising the step for carrying out the arc discharge across an anode 2 composed of a carbon electrode and a cathode 3 arranged oppositely to the carbon electrode and composed of a heat-resistant electroconductive material and a step for collecting a deposit produced on the cathode surface therefrom.
