Fullerene C60 was proposed by Crott and Smoulay et al., Rice University in Houston, USA, in 1985. They bombarded graphite with a high-power laser beam to vaporize it, and used helium gas at 1MPa pressure to generate ultrasonic waves, so that the carbon atoms vaporized by the laser beam entered the vacuum through a small nozzle to expand, and cooled rapidly, thus obtaining C60. The composition and structure of C60 have been proved by mass spectrometry, X-ray analysis and other experiments. In addition, many molecules similar to C60, such as C70, have also been discovered. In 1991, scientists found that C60 has superconductivity after mixing a small amount of certain metals, and the production process of this material is simpler than the production of traditional superconducting materials - ceramics, the texture is very hard, so it is predicted that the use of C60 in superconductivity may exceed ceramic materials.
