In-Sm (Indium-Samarium) H. Okamoto The assessed phase diagram for the Sm-In system is based on the experimental analyses of [81Sha] and [82Sac], with review of the data of [74Die]. When disagreements between the data of [81Sha] and [82Sac] were noted, the data of [ 82Sac] were accepted because the investigation of [82Sac] was more detailed. [82Sac] observed that the Sm3In5 phase exhibits a small solubility range and a slight shift in stoichiometry toward a composition richer in Sm. The solubility of Sm in liquid In was measured by [74Die] in the temperature range between 400 and 500 C: log C = 0.77 - 1300/T, where C is in at.% Sm and T is in K. According to this expression, the L/[L + SmIn3] liquidus composition near the melting point of In is 99.994 at.% In. Therefore, the solubility of Sm in (In) must be much less than 0.006 at.%. Accordingly, the eutectic temperature is only slightly lower than the melting point of In. The N‚el temperature of SmIn3 is 16 K [69Bus]. 60Ian: A. Iandelli, Att. Accad. Naz. Lincei, Rend. Cl. Sci.
