Abstract

X-ray diffraction studies were used to investigate the wide solubility range of Ga in RGa2 type compounds observed in several systems of light rare earth metals (= R) with Ga. A model, based on pairwise substitution of R atoms by Ga atoms, is suggested to explain the observed wide solubility. Using this model it is possible to explain the change in lattice parameters of the ε phase having the formula R(1-x)Ga2(1+x). The structural relationships among the phases RGa2, R(1-x)Ga2(1+x,RGa6, and pure Ga are delineated, and the common feature of these phases which belong to widely different crystal systems is shown.
