Research on Phases and Morphology of Fe-Se powders Synthesized by Hydrothermal Method
The Fe-Se powders have been prepared by hydrothermal method at temperatures of 160,180 and 200 ℃C from FeCl3·6H2O and SeO2.The phases and morphology of the products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) respectively.Experimental results show that,the major phases of these product powders are all FeSe2,the impurity phase Se can be identified in spite of poor crystallinity of all samples.The poor crystallinity becomes seriously at lower synthesizing temperature under the experimental conditions.These product powders consist of grains,rods or flakes with sizes of 20~300nm,among which the product obtained at 180 ℃ has the smallest size of 20~40nm.
