In-Te (Indium-Tellurium) H. Okamoto The assessed phase diagram for the In-Te system is based primarily on [34Kle] and [64Gro], with review of the data of [65Pal] and [80Shc], and has been modified to reflect additional information on the relationship between bIn2Te3 and aIn2Te3 from [62Hol] and [70Gal] and on the liquid miscibility gap at compositions below ~30 at.% Te from [71Wob]. The In-richest phase is In4Te3 [ 73Hog]. The critical temperature of the miscibility gap is 533 C [71Wob] or 528 C [ 80Shc], but not as high as the ~600 C postulated by [64Gro]. The composition of the critical point is 18 at.% Te [71Wob]. The compositions of the two liquids at 450 C are 6.9 and 27.2 at.% Te, respectively [80Shc]. The In side of the assessed diagram is based tentatively on [71Wob], who gave the most detailed data in this composition range. Because the solubility of Te in In(L) is small (<< 1 at.%), the eutectic temperature must be only slightly below the melting point of In; it is shown at 156 C in the assessed diagram. If the reaction is eutectic, the solubility of Te in (In) must be very small. No solubility of In in (Te) is known. In2+xTe3, with a composition between InTe and In2Te3, was found by [63Sem]. Because of the similarity in the lattice parameter, this is probably the same as a phase found later by [65Dek], [67Tol], [68Dek], and [68Ves] in a thin film, also with a composition between In2Te and In2Te3 (In3Te4 is speculated in [67Tol]). In2Te3II in a metastable and metallic form was found by [39Lan], [64Jay], and [ 64Gel]. In2Te3 in a hexagonal form was found in a thin film [70Bar]. In-Te alloys containing 70 to 90 at.% Te become amorphous when quenched from the liquid state [63Luo]. Amorphous InTe films were obtained by thermal sputtering of single-crystal samples on unheated substrate in a vacuum of about 10-3 Pa [73Pol]. InTeII, the NaCl-type high-pressure modification of InTe, was reported by [ 63Ban], [64Jay], and [85Ome]. The transition between InTeI and InTeII under hydrostatic pressure is accompanied by a hysteresis effect whose magnitude increases so markedly at lower temperatures that InTeII can be retained at ambient pressure [85Ome]. The transition between the two liquids (L and L›) is attributed to the conversion of the In cations from univalent to trivalent with a decrease in volume [85Ome]. InTeII may be obtained at >32 kbar under high temperatures [63Dar]. InTeII forms by melting at 40 to 50 kbar and 1100 C [63Ban]. It also forms by transformation of InTeI at 28 kbar and >150 C [63Ban] or 50 kbar and 150 C [ 64Scl]. InTeII can be retained at 1 bar pressure and <125 C by quenching to liquid nitrogen temperature (-195.80 C) [63Dar]. InTeII undergoes a transition to CsCl-type InTeIII at about 150 kbar [85Cha]. The superconducting transition temperature of InTeII is 2.18 K [64Jay] or 3.2 to 3.45 K [64Gel]. It decreases almost linearly with increasing Te content to ~1.04 K at 54.9 at.% Te [64Gel]. Tetragonal InTeII› exists as a transitory phase during the InTeII = InTeI transformation at 1 bar [65Scl]. When In2Te3 is subjected to pressures above 25 kbar, it undergoes a phase transformation to In2Te3II, accompanied by a large drop in resistivity [64Jay]. The superconducting transition temperature is 1.0 K [64Jay]. 34Kle: W. Klemm and H.U. von Vogel, Z. Anorg. Chem., 219, 45-64 (1934) in German. 39Lan: P.W.
