Abstract
Carbon nanotubes have become one of the studying hot points in the current of material field because of its special properties and unique structural features. In order to discuss the formation mechanism of carbon nanotubes in nature, the carbon nanotubes occurred in Sujiquan graphite ore deposit, Xinjiang has been analyzed by micro Raman spectroscopy. The characteristic of first-order is that there exists vibration peak E2g in layer of graphite inhered and locates at 1580 cm− 1 ; the vibration peak in layer caused by the deficiency of original structure and locates at 1346cm− 1.The characteristic peak of natural carbon nanotubes has not been found at 0 to 200 cm− 1,while there is obvious raman peak at 460cm− 1 and 1087 cm− 1.The inner tube is concluded to be single walled carbon nanotubes with a diameter of 0.5nm according 460cm− 1.
