Hg-In (Mercury-Indium) H. Okamoto The assessed Hg-In phase diagram is essentially the same as in [Metals], except for minor modifications in temperatures and compositions of invariant reactions. The assessed diagram was based primarily on [64Mor], [66Cla], and [ 70Hel], with review of the data of [51Ito], [53Spi], [61Koz], [62Chi], [62Egg], [62Jan], [63Col], [69Koz], [70Koz], and [70Mas]. However, significant inconsistency was found in the identification and stoichiometries of intermediate phases and their homogeneity ranges. The maximum melting temperature of (Hg) is -15 C, occurring at about 14.3 at. % In, where Hg6In was previously believed to melt. Reports on the temperature dependence of the solubility of Hg in (In) are contradictory. According to [54Tyz], an (In) alloy with 6.45 at.% Hg quenched from 94 C was fct, which transformed to fcc after 1 month at room temperature. [63Col] observed that a 7 at.% Hg alloy quenched from 85 C was cubic, transforming to two-phase cubic + fct after holding at room temperature for 6 weeks. At about -78 C, it was wholly tetragonal, presumably having transformed martensitically. The assessed value is based on [63Col]. However, redetermination of the fcc = fct transition boundaries is needed because of the conflicting reports. [63Mer] measured the superconducting transition temperature (Tc) of Hg-In phases for the entire composition range. All phases become superconducting with Tc higher than 3 K. e shows the highest Tc (4.5 K) at the Hg-richest end of the homogeneity range (~80 at.% In). Tc for each phase decreases rapidly with increasing In content in the homogeneity range of each. Tc of (In) shows a minimum at 1.75 at .% Hg [60Ree], which is 3.4 K [ 63Mer]. 51Ito: H. Ito, E.
