In-Tm (Indium-Thulium) H. Okamoto The assessed Tm-In phase diagram is based primarily on the work of [83Yat], with review of the experimental data of [74Die]. The accuracy of the temperature scale may be no better than с5 C, because all temperatures in [ 83Yat] are rounded to the nearest 10 C. The existence of a b = a allotropic transition in pure Tm has not been well established. Therefore, "(bTm)" may be an impurity-stabilized phase. Although it has never been identified positively, the existence of Tm3In5 is almost certain according to similarity in the Tm-In and Er-In phase diagrams [83Yat]. The solubility of Tm in liquid In was measured by [74Die] between 400 and 500 C; log C = 0.786 - 1160/T, where C is in at.% Tm and T is in K. According to this expression, the eutectic composition is 99.988 at.% In. Therefore, the assessed diagram shows that the solubility of Tm in (In) is negligible and the eutectic temperature is only slightly lower than the melting point of In. 64Kuz: Yu.B. Kuz'ma and V.Ya.
