Abstract
At low temperature, a reduction reaction between TiCl4 and Na in liquid ammonia was conducted for the preparation of TiN nanoparticles. According to the result of XRD and TEM analysis, the synthesized powders are stoichiometric cubic phase TiN and particle sizes are less than 20 nanometers. The micro-TiN and synthesized nano-TiN powders were densified by SPS. The results showed that it was difficult to completely hinder the nano-TiN grain growth during SPS process and final product with grain size of 100-150nm was obtained. While, sintering temperature of nano-TiN was lower than that of micro-TiN, and that much higher density was obtained.
