Mesopoures Titanium carbide nano powders and nano whiskers were synthesized by the sol-gel process using phenolic resin and titanium alkoxide as precursors. The effect of synthesis temperature and soaking time on the free carbon content and the formation and morphology of TiC nano powders was investigated. It was found that titanium carbide began to nucleate at a temperature of approximately 1200°C and ended at 1400°C. Surface studies revealed that the pores on the surface of the synthesized nano powders were in the meso range and had a specific surface area of 150m2/g. Microstructural images indicated that over time, TiC nano whiskers nucleated heterogeneously from the particle surface and grew in a soaking time of 3 h. The free carbon content detected in the synthesized product under a soaking time of 3 h was reported to be less than 1%.
