Titanium silicon carbide Ti3SiC2 was synthesized from a powder blend of Ti; Si and TiC at a molar ratio of Ti:Si:TiC = 2:2:3. The powder blend was pressed and shaped into a cylinder and then sintered at various temperatures in vacuum. X-ray diffraction analysis was conducted on the cylinders sintered at various temperatures. Results of the XRD analysis revealed that Ti5Si3; the most thermodynamically stable phase in Ti-Si system; was preferentially formed by the reaction between Ti and Si powders followed by the formation of TiSi2 from remaining Ti and Si powders in a relatively low temperature range. These silicides reacted with TiC to form Ti3SiC2 at higher temperatures. The final phases in the cylinders sintered at temperatures over 1729 K were Ti3SiC2 and Ti5Si3; which well agrees with those estimated by a Ti-Si-C phase diagram. On the other hand; final phases in disks sintered under pressures of 14 MPa or more by using a carbon mold were found to be Ti3SiC2 and TiC; which suggests the equilibrium changes with the pressure. © 2006 Elsevier B.V.
