摘要：
A benzene-thermal reaction of TiCl4 and NaN3 at 350°-380°C was unducted for the preparation of nanocrystalline TiN. Powder X-ray diffractometry patterns indicated that the powder was cubic-phase TiN with a lattice constant a = 4.23656 angstrom. Transmission electron microscopy images showed the TiN powder consisted of uniform spherical particles with an average diameter of 50 nm. The binding energies of Ti 2p3/2 and N 1s core levels at the positions of 454.85 and 397.1 eV, respectively, and the Ti:N atomic ratio of 1.08:1.00 were detected by X-ray photoelectron spectra. A possible formation mechanism of TiN was proposed.
