摘要

Nanocrystalline NiSb and NiSb₂ have been prepared through a solvothermal co-reduction route at low temperatures (120–180 °C). The features of this method include: (1) the reactants are simple inorganic salts (NiCl₂·6H₂O and SbCl₃); (2) two types of nickel antimonides (NiSb and NiSb₂) can be obtained respectively by changing the reducing agents and temperatures. The as-prepared samples were characterized by XRD and TEM. A possible formation mechanism has been presented. The thermoelectric properties of as-prepared NiSb, and the magnetic properties of NiSb₂ were investigated.
