| Abstract Scope |
The higher purity of Ti2SnC ternary compounds have been successfully synthesized by self propagating high-temperature synthesis(SHS) technique with elemental Ti, Sn, C and some different Ti-Sn intermetallic compounds powders as raw materials. The molar ratio of Ti/Sn/C was set 2:1:1. The result shows that the additions of Ti5Sn3 and Ti2Sn play a different role in synthesis of Ti2SnC and the optimum addition content are both 20%. Meanwhile, the reaction mechanism for the formation of Ti2SnC in the system is confirmed that Ti5Sn3 intermetallic compounds react with TiC to form Ti2SnC, rather than Ti2Sn. And Ti2SnC will partly decompose into Ti5Sn3 and TiC at higher temperatures. |
