Preparation of Ternary Layered Ti3SiC2 Ceramic by SHS/PHIP

摘要：

　　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.
