摘要：

A novel method based on the solid-liquid reaction in the Ti-Sn-C system was developed for the synthesis of Ti2SnC powders. In this process, Ti-Sn intermetallic compounds were formed in liquid Sn, then they further reacted with graphite powders to form Ti2SnC. The advantages of this solid-liquid reaction based method include low synthesis temperature, short reaction time and less impurity in the as-prepared powders. Investigations on the stability of Ti2SnC powders demonstrated that Ti2SnC was stable in Ar up to at least 1200 degreesC. In air, however, a complex oxidation-decomposition-oxidation process was observed.
