Abstract

The formation of the structure of semiconductor compositions α-Fe-C60 and α-Fe nanotubes is studied at 650 and 880°C. The concentration of fullerenes and nanotubes varied from 1 to 2 wt %. The samples were pressed at 600 MPa. It is shown that the fullerene of compositions α-Fe-fullerene partially transforms into graphite while another part interacts with Fe. As a result of this interaction, fullerene-containing Fe x C60 phases are formed. At 880°C, fullerenes decompose more intensely than at 650°C. It is established that, during the sintering of composition Fe nanotubes at t = 650 and 880°C, the nanotubes partially decompose with the formation of fullerene-containing phases and this process is more active at 650°C than at 880°C. An increase in the amount of nanotubes introduced into the compositions leads to the activation of the synthesis of fullerenes.
