Nd-Rh (Neodymium-Rhodium) Editor [70Sin] determined the Nd-Rh phase diagram by powder X-ray diffraction, metallographic, and differential thermal analysis methods. The crystal structures of "Nd3Rh," "Nd5Rh3," and "Nd4Rh3" were undetermined. [76Ram] (one of the authors of [70Sin]) disclosed that "Nd4Rh3" is actually Nd5Rh4. Because crystal structures of compounds with similar compositions were determined, Nd7Rh3 is shown instead of "Nd3Rh" and Nd3Rh2 is shown instead of "Nd5Rh3" in the diagram. [70Sin] reported that "Nd5Rh3" is polymorphic with an unknown transformation temperature.-H.O. 59Com: V.B. Compton and B.T. Matthias, Acta Crystallogr., 12, 651-654 (1959). 63Dwi: A.E.
