摘　　要：在水热环境中,以EDTA作为螯合剂,加入NiSe2作为晶种,在碱性条件下合成CoS2粉体.借助X射线衍射(XRD)对所得产物的晶相组成进行表征,并用Rietveld法对样品进行结构精修,结果表明,样品为AB2型立方结构,空间群Pa3,晶格常数a=5.5340.CoS_2 powder was synthesized by EDTA-assisted hydrothermal method under alkali conditions, adding NiSe_ 2 as seeds. X-ray diffraction (XRD) was used to characterize the structural features of sample.The XRD pattern was refined by Rietveld method. The refinement data indicate that the products are AB_2 cubic system, spacegroup Pa-3, lattice constant a=5.5340*!.
