Notes:
Ternary-layered Ti3SiC2 ceramic was prepared by self-propagation high temperature combustionsynthesis with pseudo hot isostatic pressing (SHS/PHIP). The effect of Ti/C mol ratio, Si content andAl content on the phase composition of the products was investigated. Experimental results showed thatthe phase composition of SHS/PHIPed products was influenced greatly by Ti/C mol ratio and Si contentin the raw material. When Ti/C mol ratio is 1.5, the main phase was TiC with only a little Ti3SiC2; thecontent of Ti3SiC2 increased greatly with increase of Si content. The main phase turned to Ti3SiC2 whileTiC became the main impurity when the Ti/C mol ratio arrived at 2. With addition of aluminum, thecontent of Ti3SiC2 increased obviously and the distortion of lattice was caused in Ti3SiC2 crystals
