TiC particulates were prepared by self-propagating high temperature synthesis (SHS). The effect of elemental aluminum on the formation of TiC particulates was particularly studied by differential thermal analysis (DTA) and sintering experiments of Ti-C-Al system. The sintered products were examined by XRD and TEM. The results showed that Ti did not react with C directly in the absence of elemental Al. The sintering process of Ti-C-Al system presented typical high-temperature self-propagating synthesis (SHS) features. TiC particulates could be maximally obtained through the appropriate control of the Al content in the system. The size of the resultant TiC particulates was about 0.15μm.
