【摘要】 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亚稳相更多还原

【Abstract】 Results of XRD and Raman spectra show the successful preparation of lamellar structural materials Ni2P2S6 by a new synthetic route room temperature solid state reaction. Compared with the traditional high temperature solid state reaction, the preparation method adopted here has the following advantages: fast reaction rate, low energy cost, high homogeneity of final products and the facility of preparation in quantity. Study of TG\|DTA shows the final product Ni2P2O7 and the existence of an intermediate metastable Ni2P2O6 phase of Ni2P2S6 thermo\|oxidation in air.更多还原
