PURPOSE:To make it possible to manufacture metal contained fullerene with high efficiency by using an electrode available from the mixing and sintering of metals with easily graphitized carbon as a positive electrode and arc discharging the electrode inside a vacuum chamber and separating fullerene from the deposits. CONSTITUTION:A hole is bored in the center of a high purity graphite rod 3a and metal containing-carbon powder 3b is put into the hole, thereby producing a positive electrode 3 while the high purity graphite rod is used as a negative electrode. The positive and negative electrode 2 and 3 are installed in a chamber 1. Then, DC current is made to flow between the electrodes 2 and 3 from a DC power source 6 while the air in the chamber is being replaced with an inert gas. Then, arc discharging is produced between the electrodes 2 and 3 where soot called fullerene attaches to an inner wall 1a of the water-colled chamber. The removed soot is put into a quartz tube 8. While the inside the tube is being evacuated into high vacuum, the temperature is increased by using a heating device 9. A substance 10 sublimated from a filler 7 is cooled at the upper part of the quarts tube 8 and deposited. This construction makes it possible to provide metal lanthanum containing fullerene which is thermally stabilized. |
