TiN nanopowder was synthesized by carbothermal reduction method by using a (TiO 2 +C) precursor derived from titanyl nitrate, urea, glucose, ammonium nitrate, and citric acid mixed solution. The results revealed that the obtained precursor consisted of flake particles with a uniform dispersion of amorphous TiO 2 and C. The precursor powders were subsequently calcined under nitrogen at 900–1300°C for 2h. The initial transformation of TiO 2 to TiN, by adopting this route, occurred at 900°C. Moreover, TiO x N y , TiO 2 , and carbon below 1200°C, and TiC x N y , TiO x N y , TiO 2 , and carbon at (or above 1200°C) were found to be as impurities with the calcined products. The lattice parameter of TiN synthesized at 1100°C (α=4.240Å) agrees well with the theoretical value (α=4.241Å). TiN powder, synthesized at 1100°C, exhibited well-distributed spherical particles ranging from 80 to 100nm. The nitrogen, oxygen, and residual carbon contents of TiN powder synthesized at 1100°C were found to be 20.37wt.%, 1.91wt.%, and 3.36wt.%, respectively.
