摘要：
This work is devoted to microwave heating of graphite to produce carbon nanotubes (CNT's). We have applied heating by microwaves (MW) (power 800 W, frequency 2.45 GHz) in vacuum (10(-5)Torr) at 30-90 min. The oven temperature was approximately 1200 degrees C. The condensed material was collected on a fused silica target. After deposition, the morphology of carbon nanotubes was studied by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The samples were found to contain nanotubes, nanoparticles and fibers (1-2.8 micrometers). It was observed that multi-walled nanotubes (MWNTr's) were produced by this method.
