以钛、TiC、硅粉为原料，采用反应熔渗烧结法制备了Ti3SiC2材料，并对其抗弯强度及断口形貌进行了分析。结果表明：将物质的量比为1：2：0．2的钛、TiC、硅粉混合后，在1500℃烧结0．5h，能够制备出高纯致密的Ti3SiC2材料，Ti3SiC2的纯度高达97．6％，孔隙率仅为4．6％；随着Ti3SiC2材料纯度的增加，材料的抗弯强度明显提高，当Ti3SiC2材料的纯度为97．3％时，其抗弯强度达到252．5MPa断口可见大量层状Ti3SiC2颗粒，颗粒间无明显的界面。
Using Ti, TiC and Si powders as raw materials, Ti3SiC2 material was prepared by reactive melt infiltration sintering process. The flexural strength and fracture morphology of the material were analyzed. The results show that highly pure and compact Ti3SiC2 material, whose Ti3SiC2 purity and porosity were 97. 6% and 4.6% respectively, could be obtained with the molar ratio of 1 ： 2 ： 0. 2 （Ti, TiC and Si powders） after sintering at 1 500 ℃ for 0. 5 h. With increase of the Ti3SiC2 content, the flexural strength increased obviously, when purity of Ti3 SiC2 material was 97. 3 %, the flexural strength could reach 252.5 MPa. A lot of layered Ti3SiC2 particles on the fracture, and there was no obvious interface between particles
