A novel process for synthesizing nano-ceramics powders, named mechanical & thermal activation processing, is discussed in the present paper It is a processing based on thermal activation in liquid phase (molten salt) after mechanical activation. The nanometer-sized TiC particles (15-20nm) have been synthesized by the method, and analyzed by X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscopy (SEM) and energy dispersion X-ray (EDX) spectroscopy. An interface interaction between liquid (molten salt) and solid (final product particles) phases plays a dominating role for the control of product particles size. The mechanism for the formation of nanometer-sized TiC particles has been discussed.
