摘要：

From the results obtained by differential thermal analysis and X-ray diffraction, the state diagrams of the binary systems R-Ga where R = Se, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu are proposed. The liquidus line near Ga has been determined using the solubility data of R in liquid gallium. The previously unknown compounds Sc5Ga4, ScGa2, ScGa3, EuGa, DyGa3, Er2Ga3, Tm2Ga3, TmGa2, YbGa, Lu2Ga3 and LuGa2 are found. ScGa3 crystallizes in a cubic structure of the AuCu3 type. A short discussion of the change in the thermal stability of the intermediate phase and its dependence on the order number of the component R is given. © 1979.
