Synthesis of novel acceptor type graphite intercalation compounds and its superconductivity

以石墨片（GS）和剥落石墨片（ExGS）为主体材料，在350℃的硫中浸泡24 h，在空气气氛下合成了S-GIC（石墨插层化合物）。在x射线衍射图上发现了与基体材料或插入的硫不对应的新峰。指出了插层化合物的形成过程。然而，在惰性气氛（如N2）下合成S-GIC时，没有在相同的条件下进行。在空气中合成的新峰的确认是不可能的。

Synthesis of S-GIC (graphite intercalation compounds) was carried out by soaking the graphite sheet (GS) and Exfoliated graphite sheets (ExGS) which is the host materials in the sulfur which melted at 350 oC for 24 h under air atmosphere. New peaks which did not correspond to host materials or the sulfur which is intercalated was able to confirm it on XRD pattern. Formation of the intercalation compounds were indicated. However, in the case of synthesis of S-GIC under inert atmosphere such as N2, it was not carried out in the same conditions. The confirmation of new peaks recognized in the synthesis in the air was not possible in it.
