A Thermodynamic Study of the Zinc-Antimony System. The Thermodynamic Properties of the Intermetallic Compounds: ZnSb, Zn₃Sb₂ and Zn₄Sb₃

Stability, electronic structures and thermoelectric properties of binary Zn–Sb materials

“…Previous studies on the phase diagram of the zinc-antimony system have reported compound Zn 3 Sb 2 . 41,42 But it is metastable and crystals amorphize over time, which impedes its structure and property characterization. We performed a crystal structure prediction for Zn 3 Sb 2 via global minimization of free energy surfaces as implemented in the CALYPSO code, which searches for the stable structures of the given compounds.…”

A thermodynamic assessment of the Sb–Zn system

“…The thermodynamic properties of liquid alloys and Sb-Zn compounds were studied by various experimental methods [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. They are reviewed in the following subsections.…”

“…Electromotive force (EMF) measurements were performed by DeWitt and Seltz [25], Kleppa and Thalmayer [26], Kozuka et al [27], Gerasimenko et al [28], Rubin et al [29], Ptak and Zabdyr [30], Gerling and Predel [31] and Seltz and De Witt [32] to determine the thermodynamic properties of the liquid phase. The enthalpies of mixing of liquid alloys were measured by means of calorimetry by Kawakami [33], Scheil and Lukas [34] Table 1 Literature details of measurements on the phase diagram…”

“…DeWitt and Seltz [25] deduced the standard thermodynamic properties of the three compounds SbZn, Sb 3 Zn 4 and Sb 2 Zn 3 from both the liquidus and the activities of elements in liquid phase measured by EMF. The EMF method was also employed to determine directly the thermodynamic properties of compounds by Zabdyr [39], Goryacheva and Geiderikh [40] and Goncharuk and Lukashenko [41].…”

Impurity band conduction in the thermoelectric material ZnSb

“…2.2 [60]. The phases ZnSb, Zn 3 Sb 2 and Zn 4 Sb 3 have been well-recognized for a long period[60,[64][65][66]. Zn 4 Sb 3 has been much studied due to its phonon-glass electron-crystal structure that leads to a remarkably low thermal conductivity, typically 0.65 W/m•K at room temperature…”
