A nano-laminated Y₃Si₂C₂ ceramic material was successfully synthesized via an in situ reaction between YH₂ and SiC using spark plasma sintering technology. A MAX phase-like ternary layered structure of Y₃Si₂C₂ was observed at the atomic-scale by high resolution transmission electron microscopy. The lattice parameters calculated from both X-ray diffraction and selected area electron diffraction patterns are in good agreement with the reported theoretical results. The nano-laminated fracture of kink boundaries, delamination, and slipping were observed at the tip of the Vickers indents. The elastic modulus and Vickers hardness of Y₃Si₂C₂ ceramics (with 5.5 wt% Y₂O₃) sintered at 1500 °C were 156 and 6.4 GPa, respectively. The corresponding values of thermal and electrical conductivity were 13.7 W·m^-1·K^-1 and 6.3×10⁵ S·m^-1, respectively.

利用火花等离子体烧结技术，通过YH ₂与SiC的原位反应成功地合成了纳米叠层的Y ₃ Si ₂ C ₂陶瓷材料。通过高分辨率透射电子显微镜在原子尺度上观察到了Y ₃ Si ₂ C ₂的MAX相状三元层状结构。由X射线衍射和选定区域电子衍射图谱计算得到的晶格参数与报道的理论结果非常吻合。在维氏凹痕的尖端观察到了纳米层的扭结边界，分层和滑移。Y的弹性模量和维氏硬度在1500°C下烧结的₃ Si ₂ C ₂陶瓷（Y ₂ O ₃含量为5.5 wt％）分别为156 GPa和6.4 GPa。相应的热导率和电导率分别为13.7 W·m ^-1 ·K ^-1和6.3×10 ⁵ S·m ^-1。
