In this article, fabrication of SiC nanotubes (SiCNTs) by using different ratios of single-walled carbon nanotubes to SiO 2 nanopowders (3:1, 2:1 and 1:1) is presented. In order to develop SiCNTs, shape memory synthesis (SMS) had been employed. Argon gas, the carrier gas was introduced into a furnace, heated to 1350°C at a heating rate of 16°C/min and the temperature was kept for 4h. X-ray diffraction analysis verified that different polytypes of SiCNTs were formed through SMS method. The microscopy analysis revealed that the amount and morphology of SiCNTs synthesized was dissimilar when different ratios were used.
