“…The CALPHAD method has been used with advantage. This method allowed us to predict the phase diagram using the data from binary subsystems [7][8][9] and to plan the experiment effectively. Experimentally, only one ternary phase was found in some samples, referred to as Sb 2 SnZn.…”

“…The CALPHAD approach implemented in the PANDAT 2012 program was used for the prediction of isothermal sections of Sb-Sn-Zn phase diagrams. COST 531 database optimized for solders (SOLDER) and updated with the published information about Sb-Sn [9] and Sb-Zn [8] subsystems was used for the calculation of phase diagrams.…”

“…[18] Relevant thermodynamic database can be used to calculate equilibrium phase diagrams of binary subsystems, here Sb-Sn, [9] Sn-Zn, [7] and Sb-Zn. [8] The method also allows us to predict the ternary phase diagram of the Sb-Sn-Zn system, as the authors used before [19] and here for better understanding of the obtained experimental results.…”

International. This e-offprint isExperimental Study of the Sb-Sn-Zn Alloy System ONDREJ ZOBAC, JIRI SOPOUSEK, JIRI BURSIK, ADELA ZEMANOVA, and PAVLA ROUPCOVA The Sb-Sn-Zn alloy was prepared and researched by experimental methods, which allow obtaining information on the thermodynamic stability of the coexisting phases. Thermal analysis was used to determine the phase transition temperatures of experimental alloys. Equilibrium composition of coexisting phases after long-term temperature equilibration was determined by electron microscopy. The existence of one ternary stoichiometric phase Sb 2 SnZn was experimentally confirmed by diffraction technique. The CALPHAD method for prediction of the phase diagram of the Sb-Sn-Zn system from binary subsystems was used in this work.

“…At the pressure required to adjust the calculated Zn 8 Sb 7 lattice parameter to the experimental value (À3.4 GPa), the energy correction is 3 meV/atom in favor of Zn 8 Sb 7 . We suggest that through some combination of surface energy and lattice strain, Zn 8 …”

“…The small particle size of the reactants ensures minimum diffusion paths, low activation barriers, and low reaction temperatures, thereby eliminating solidÀsolid diffusion as the rate-limiting step as found in conventional bulk-scale solid-state synthesis. 4 In the present work, the authors denote this new phase as Zn 8 Sb 7 , based on the idealized crystal structure, rather than Zn 1+δ Sb (with δ = 0.068) as used in ref 4.…”

Predicted Electronic and Thermodynamic Properties of a Newly Discovered Zn₈Sb₇ Phase

et al. 2011

A new binary compound, Zn8Sb7, has recently been prepared in nanoparticulate form via solution synthesis. No such phase is known in the bulk phase diagram; instead, one would expect phase separation to the good thermoelectric semiconductors ZnSb and Zn4Sb3. Here, density functional calculations are employed to determine the free energies of formation, including effects from vibrations and configurational disorder, of the relevant phases, yielding insight into the phase stability of Zn8Sb7. Band structure calculations predict Zn8Sb7, much like ZnSb and Zn4Sb3, to be an intermetallic semiconductor with similar thermoelectric properties. If sufficient entropy or surface energy exists to stabilize the bulk material, it would be stable in a limited temperature window at high temperature.

The field of thermoelectric materials has flourished over the last two decades. Significant successes achieved in the development of materials notwithstanding, novel and highly efficient materials are in steep demand due to a wide range of potential and current applications, ranging from wearable electronics to space missions. The main challenge in the improvement of the thermoelectric figure of merit ( zT ) is to optimize the intertwined intrinsic charge and thermal transport properties. High electrical conductivity and thermopower, along with low thermal conductivity, need to be achieved simultaneously to excel the thermoelectric efficiency. In this review, the thermoelectric concepts, basics of transport properties, and strategies for zT optimization are discussed in the first section. In the following sections, the predominate structure types associated with high‐performance bulk thermoelectric materials are discussed in detail: Bi 2 Te 3 , PbTe, TAGS/LAST systems, SnSe, Cu 2− x Se, chalcopyrites, tetrahedrites, clathrates, skutterudites, zinc antimonides, Yb 14 MnSb 11 , Heusler and half‐Heusler intermetallics. The basic crystal structures, the possibilities for doping and substitutions to adjust charge carrier concentration and thermal conductivity, baseline thermoelectric properties, and strategies for efficiency improvement are considered for each structure type. Examples of recent work highlighting these strategies are briefly presented.
