Abstract

The self-propagating high-temperature synthesis (SHS) method has been applied to the preparation of TiC powder from mixtures of TiO2, Mg, and C. The TiC/MgO product is leached by hydrochloric acid to remove the MgO. The optimum mixing ratio was TiO2∶Mg∶C=1∶2.2∶1.5. The final product TiC had > 99.9% purity and relatively uniform particle size of 0.3–0.4 μm.
