New high-tin phase found in electrolytic Sn–Ni deposits

摘要

Using X-ray diffraction technique and transmission electron microscopy it has been demonstrated that multiphase Sn–Ni electrodeposits with 3–34 at.% Ni contain a new phase of composition close to NiSn9. Its lattice parameters are specified as follows: a 0 = 1.2621(7), b 0 = 0.5231(4), c 0 = 0.6213(4) (in nm), β = 105.8(7)° of the C 2/m space group. This new phase decomposes at 100°C into β tin and Ni3Sn4.
