摘要：

The ytterbium-gallium system has been investigated by differential thermal analysis, X-ray diffraction and metallographic analysis. Four intermediate phases have been found to exist in this system, namely Yb2Ga, YbGa, YbGa2 and YbGa4. Yb2Ga and YbGa were not previously known and their crystal structures have been completely determined. The structure of YbGa2 has been confirmed while for YbGa4 a slightly different structure, probably derived from the BaAl4 type, was found in this work. Eutectic points occur at 21.5 at.% Ga (605°C), 53.5 at.% Ga (880°C) and about 99.0 at.% Ga (27°C). No appreciable solid solubility of Yb in Ga or of Ga in Yb has been observed and the four intermediate phases appear to be line compounds. © 1979.
