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