Reviewer 2 Report
The submitted paper provides review, critical evaluation, and thermodynamic modeling of Cu-Se-Zn binary subsystems. The review and critical evaluation of the thermodynamic data for these binary systems is very thorough and extensive. The resulting modeling work appears to be of high quality and show significant improvements in the phase diagrams and thermodynamic properties compared to the previously published work that is compared in the analysis.
This reviewer recommends this paper for acceptance after addressing the following minor comments:
1. Some formatting in Table 1 appears incorrect. For example, space groups for fcc and bcc are missing the “-3”, e.g. showing “Fm m” instead of “Fm-3m”. In addition, for γ-CuSe, the prototype “orthorhombisch” should be “orthorhombic”
2. Some possible placeholder text appears in the first paragraph of Section 3 (page 9, lines 307-309)
3. Coordination-equivalent fractions are used in Eq. 3, but not defined as an equation.
4. Eq. 8, subscripts appear to be incorrect for the summation notation
5. The mathematical description of the partitioned model for bcc seems incorrect and written in a non-standard way. The ordering contribution to Eq. 14 (written in Eq. 16 and 17) should be subtracting a contribution of the ordering energy where all site fractions are replaced by mole fractions.
6. In general, the figures are too small and low resolution. The inset labels are difficult to read in print form or digitally without zooming in.
7. Tabulated Calphad model parameters in publications often have typographical errors or missing information. Please include a thermodynamic database file as supplemental material so this work can be reproduced by openly available software, such as a ChemSage DAT file (usable by FactSage, Thermochimica, or PyCalphad) or a TDB (usable by Thermo-Calc, Pandat, OpenCalphad, PyCalphad, etc.).
