- 論文の詳細を見る
The generation of a carbon nanotube and the first stage of carbon nanotube or carbon fiber formation were investigated in arc electric discharge in a gas mixture of helium and atmosphere with a negative carbon electrode containing lithium or potassium. A carbon stick with lithium and a carbon stick with potassium appeared to accelerate the generation of the carbon nanotube. It was found that the generation of the carbon nanotube is restricted in the range of atmospheric partial pressure from 10 kPa to 20 kPa, and an ideal spherical substance with a size from one hundred nanometers to five micrometers was generated. If the atmospheric partial pressure is lower than that range, the spherical substance changes into a carbon nanotube or carbon fiber. The carbon mesocell, which includes various kinds of elements, can be produced by choosing a carbon stick with additional elements.
