The powders of carbon nanotubes (CNTs) are graphitized under condition of high temperature and pressure to transform amorphous carbon in CNTs. Measurement results, which are got through TEM, measurement of specific area, measurement of quality loss after being oxidized by CO2 and air, show that the amorphous carbon has been changed to crystalline carbon.The degree of graphitization of carbon nanotube powders is significant elevated. All these show that the properties of CNTs can be changed by means of the treatment of graphitizing.
