摘　　要：以CS2为硫源,尿素为添加剂,利用水热法在120～180℃下,合成了黄铁矿型FeS2粉晶,采用X射线衍射(XRD),扫描电子显微镜进行了结构表征,比较了反应温度对于成晶的影响,并且讨论了反应机理.FeS2 powder has been synthesixed through the hydrothermal technique at 120℃-180℃ in this paper. Structures and morphology of the final products were characterizes by X-ray powder diffraction（XRD）,scanning election microscopy（SEM）.The ef- fects of the reaction temperature on the formed phase during the hydrothermal process were also investigated. The formation mechanism of the pyrite FeS2 powders under the hydrothermal conditions was discussed.
