AbstractA high-efficiency method is developed to in-situ synthesize nanocrystalline TiC powders, nanorods, and nanosheets by using equimolar ratio of Ti powder and acetylene black, multiwalled carbon nanotubes (MWCNTs), and graphene, respectively, as precursor in eutectic NaCl-KCl molten salt at 800-900 degrees C for 2-3 h. Higher temperature and longer duration are more beneficial for TiC preparation. In addition, mechanism of TiC formation was investigated by linear scan voltammetry. Results indicate that nanocrystalline TiC is in-situ synthesized by reaction between Ti atoms, which come from disproportionation reaction of Ti(II) species in the molten salt, and C atoms on the surface of carbon sources.
