Study on the Stability of FeCl_3-Graphite Intercalation Compounds Synthesized by Molten Salt Method

采用熔盐法合成出FeCl3 石墨层间化合物 ,将其在空气或某些液体媒介中放置一段时间 ,运用XRD、TG DTG测试技术研究了FeCl3 GIC的结构稳定性与热稳定性。结果表明 ,FeCl3 GICs在空气中很稳定 ,在水、酸溶液中具有较好的稳定性 ,但在碱性溶剂及某些有机溶剂中不稳定。FeCl3 GICs的热分解温度约为 3 3 0℃。

The intercalation of FeCl 3 into graphite with molten salt method has been synthesized. Its structural stability and thermal stability both in air and some liquid media for some time were investigated by using the XRD as well as TG DTG techniques. The obtained results show that FeCl 3 GICs are quite stable in air,higher stable in water and acid liquid media,but less stable in alkalic liquid media and some organic solvents. The degradation temperature of FeCl 3 GICs is about 330 ℃.
