“…Harvey investigated also very intensively a zinc-oxide-rich region at 1275 °C and corresponding phase equilibria. As mentioned before, along the binary ZnO-In 2 O 3 edge at 1275 °C there is a series of homologous compounds (ZnO) k (In 2 O 3 ) (where k = 3-5, 7,9,11), all of which are in equilibrium with the phase Spinel, starting with the first one (ZnO) 11 (In 2 O 3 ) and finishing with the last (ZnO) 3 (In 2 O 3 ) which is in equilibrium with Spinel maximally enriched in indium. The compounds with k > 11 were not found in equilibrium with spinel at 1275 °C due to sluggish kinetics in the ZnO-rich composition range [1].…”

“…Moreover, the presence of the compound with k = 15 of the In 2 Zn k O k+3 series was almost impossible to detect with the XRD technique used in [6]. The formation of homologues series In 2 Zn k O k+3 (where k = 3-7, 9,11) was confirmed at 1275 °C in the study on the ternary system In 2 O 3 -SnO 2 -ZnO [1], while the compounds with k = 6, 13, 15 became stable at higher temperatures. The lattice constant, microstructure and electrical characteristics of In 2 O 3 ceramic doped by ZnO were investigated by Park et al [48].…”

“…The present description of the system In 2 O 3 -ZnO is based on the data reported by Moriga [6]. The series of phases with the general formula In 2 Zn k O k+3 with k = 3-7, 9,11,13,15 was modelled in form of stoichiometric oxides. The thermodynamic data of these compounds are given in Table 2.…”

“…This model has been successfully applied for the description of melts containing oxides and sulphides in our previous studies, e.g. in [8][9][10]. Solubilities in the solid state have been treated using the multi-sublattice approach which allows the description of experimentally determined solubilities.…”

The In 2 O 3 -SnO 2 -ZnO system is of special interest for applications as transparent conducting oxides and also transparent semiconductors. In the present work, a thermodynamic assessment for this system is discussed using all available experimental data on phase equilibria and thermodynamic properties. All subsystems including elemental combinations were considered in order to generate a self-consistent Gibbs energy dataset for further calculation and prediction of thermodynamic properties of the system. The modified associate species model was used for the description of the liquid phase. Particular attention was given to two significant solid solution phases: Spinel with the formula Zn (2-x) Sn (1-x) In 2x O 4 based on Zn 2 SnO 4 and Bixbyite based on In 2 O 3 and extending strongly toward the SnZnO 3 composition according to the formula In (2-2x) Sn x Zn x O 3 . In addition to the component oxides, nine quasi-binary compounds located in the In 2 O 3 -ZnO binary subsystem have also been included in the database as stoichiometric phases.

Thermodynamic modeling of the Cu-Fe-S liquid solution is carried in the framework of the modified quasichemical model. The manifold nature of Cu-Fe-S liquid solutions from highly metallic via sulfur-rich to pure liquid sulfur is described by one single Gibbs energy expression at 1 bar total pressure. The model predictive ability of an asymmetric versus symmetric approach is thermodynamically analyzed with respect to the extrapolation scheme from the binary subsystems into the ternary system. Without the need of adjustable ternary parameters predictions of sulfur potentials for the liquid phase are in line with experimental data available in the literature. High-temperature pyrrhotite optimized via the compound energy formalism and Cu-Fe-S alloy phases are taken into consideration to predict phase equilibria with the liquid solution. Four isothermal and four isoplethal sections demonstrate promising agreement between a large stock of experimental data and prediction.
