Nanocrystalline TiC was synthesized through a new reduction-carburization r
oute by using metallic Na as the reductant, and tetrachlorotitanium (TiCl4)
and carbon as Ti and C sources at 650 degrees C. The present route allowed
for the formation of nanocrystalline TIC with fine particle sizes, narrow
size distribution (8-12 nm). A possible formation mechanism for nanocrystal
line TiC was proposed.
