The Self-Propagating High-Temperature Synthesis (SHS) of Ultrafine High-Purity TiC Powder from Tio2+mg+c
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 hybrochloric 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 mu m.
