摘　　要：利用钛粉、铝粉和石墨粉混合作为原料并添加少量低熔点元素--锡粉以改变烧结温度和铝含量,采用无压烧结技术在烧结温度为1 400℃,原料Ti/Al/C的摩尔比为3∶1.2∶2下制备出三元Ti3AlC2材料。通过X射线衍射仪表征其结构,获得的Ti3AlC2的纯度为96.7%,利用场发射扫描电子显微镜研究观察其微观形貌为典型的层状结构。为进一步合成锂离子电池负极材料MXene相Ti3C2提供基础。The ternary Ti3AlC2 ceramic powders were prepared by pressureless sintering technique with the Ti powders, Al powders and graphite mixed as raw materials, and a small amount of low-melting element Sn powders were added to change the sintering temperature and aluminum content. The ternary Ti3AlC2 ceramic materials were synthesis by Ti/Al/C molar ratio of 3∶1.2∶2 at 1 400 ℃. The microstructure of Ti3AlC2 was characterized by X-ray diffraction and the purity was 96.7%. The typical layered structure morphology of Ti3AlC2 were observed by field emission scanning electron microscopy. It provides the basis for further synthesis of lithium ion battery cathode material MXene phase Ti3C2 materials.
