摘要：

Skutterudite Na1+xFe4P12 whiskers were prepared by a new hydrothermal reduction alloying method. The diameter of the whisker is about 0.5-4 mum and its L/D ratio is about 10-20. Heating temperature and time can control the diameter and length of the skutterudite whisker. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), electronic diffraction (ED), and X-ray fluorescence analysis have been employed to characterize the products. XRD and ED revealed that the whiskers obtained at 200 degreesC are cubic skutterudite with a = 7.7995 Angstrom. X-ray fluorescence analysis proved that there are sodium atoms in the skutterudite structure. The possible formation mechanism of Na1+xFe4P12 is proposed.
