The discovery of carbon nanomaterials has added to the applications of carbon and created enormous interest in their development, characterization and applications in many different fields. This study describes the production and properties of carbon nanotubes (CNT), with the aim of drawing attention to useful available information and to enhancing interest in this new highly advanced technological field for researcher and the manufacturing engineer. Single wall carbon nanotubes (SWNTs) were synthesized using DC arc discharge reactor. Then an efficient purification procedure which combines centrifugation and precipitation has been used. As shown in Scanning Electron Microscopy (SEM) micrographs the cluster of metals turns smaller and smaller and the bundles of the carbon nanotube appear more and more gradually depending on the degree of purification. The thermal behavior and stability of SWCNTs-Water has been investigated by Differential Scanning Calorimeter (DSC). Also, X-ray diffraction (XRD) of SWNT for different Y and Ni catalyst has been characterized by powder X-ray diffraction.
