MAX phase Ti₃SiC₂ has been synthesized via fast hot pressing (FHP) based on the raw materials of Ti, Si, TiC and Al powders with a molar ratio of 1:1.2:2.3:0.3. The theoretical thermodynamic calculation and DSC test were adopted to verify the feasibility of the synthetic route and sintering temperature. The X-ray diffraction (XRD) result indicated that there were few impurity phases except Ti₃SiC₂ formed in the sintered sample. The sectional morphology was observed by scanning electron microscope with almost all the platelike-shaped phases, which conformed to the morphology feature of Ti₃SiC₂. Transmission electron microscopy has been brought to demonstrate the accurate phase composition as Ti₃SiC₂ combined with the PDF card of XRD analysis.

以Ti、Si、TiC、Al粉末为原料，摩尔比为1:1.2:2.3:0.3，采用快速热压法合成了MAX相Ti ₃ SiC ₂ 。通过理论热力学计算和DSC测试验证了合成路线和烧结温度的可行性。 X射线衍射(XRD)结果表明，烧结样品中除Ti ₃ SiC ₂外几乎没有杂质相。扫描电镜观察其断面形貌，几乎全部为板状相，符合Ti ₃ SiC ₂的形貌特征。透射电子显微镜结合 XRD 分析的 PDF 卡， 证明了 Ti ₃ SiC _{2的精确物相组成。}
