摘要：

Intermetallic phases and mixtures of intermetallic phases in the Sn-Mn-C ternary system were prepared by mechanical alloying. Studies concentrated on Sn2Mn, SnMn1.77 and SnMn3C. Nanoscale two-phase mixtures of Sn2Mn-SnMn1.77 and Sn2Mn-SnMn3C were prepared and studied by electron microscopy, X-ray diffraction and Mossbauer spectroscopy. These results show that each particle is a mixture of nanoscopic grains of the coexisting phases. The grain sizes of the phases are shown to be in the 10 nm range. On the basis of the results in the Sn-Fe-C system the present investigation suggests that the materials prepared here may be suitable as anode materials for Li-ion cells.
