Abstract
An apparatus and method for the production of nanotubes, fullerene and their derivatives where, in an environment where an inert gas flows at or below atmospheric pressure, a high frequency electromagnetic field is generated and a pure or doped graphite element is subjected to the electromagnetic field and heated to vaporization to form a plasma.
Claims11
A device for the production of nanotubes, fullerene and their derivatives comprising:
- a vacuum chamber 1 having an input port 2 and an evacuation port 3;
- a graphite element 5 mounted in said vacuum chamber 1;
- vaporizing means for vaporizing said graphite element 5 from said graphite element 5 and simultaneously forming a high temperature plasma around said graphite element 5;
- said vaporizing means comprising an inductor 8 mounted inside said vacuum chamber 1 and a high frequency power generator 9 operatively connected to said inductor 8 to create a strong high frequency electromagnetic field around and in a core of said inductor 8 with eddy currents;
- and
- an inert gas source delivered to flow around said inductor 8 and said graphite element 5.
