Utilizing self-combustion synthesis and high pressure generated by underwater-shock wave, titanium carbide (TiC) with high density was fabricated in this study. Also the process which denser TiC compacts can be obtained was established. Titanium and charcoal activated powders were used as raw materials, which were mixed at range from 0.6 to 1.0 of C/Ti atomic ratio. The combustion velocity was accelerated with increasing quantity of the charcoal activated powder. Density and micro Vickers hardness of the TiC compacts became higher as C/Ti ratio increased. TiC_<1.0> compact indicated maximum values of 4.72×10^3 Kg/m^3 and 32 GPa, respectively. It is expected that TiC compacts with excellent mechanical properties which compare to commercial TiC product may be obtained because the present compacts indicated similar fracture morphology to the commercial product.
