摘要：

Fabrication of monolithic Ti3SiC2 has been investigated through the route of reactive sintering of Ti/Si/2TiC mixtures. Significant phase differences existed between the surface and the interior of as-synthesized products due to the evaporation of Si during the reaction process. The use of a 3Ti/SiC/C mixture as a powder bed could control the evaporation of Si and develop monolithic Ti3SiC2. A reaction model for the formation of Ti3SiC2 in the Ti/Si/2TiC system is discussed.
