通过室温固相反应合成了Ｎｉ２Ｐ２Ｓ６层状结构材料，并经ＸＲＤ和Ｒａｍａｎ光谱进行了表征．与传统的高温固相反应法相比较，该法具有反应速度快、能耗低、可得均相产物的优点．ＴＧ－ＤＴＡ研究表明，Ｎｉ２Ｐ２Ｓ６在空气中热氧化的终产物为Ｎｉ２Ｐ２Ｏ７，中间态可能是Ｎｉ２Ｐ２Ｏ６亚稳相
Ni2P2S6 layered structure was synthesized by solid state reaction at room temperature and characterized by XRD and Raman spectroscopy. Compared with the traditional high-temperature solid-phase reaction method, this method has the advantages of fast reaction, low energy consumption and homogeneous product. The results of TG-DTA show that the final product of thermal oxidation of Ni2P2S6 in air is Ni2P2O7, and the intermediate state may be the metastable phase of Ni2P2O6
