A thermodynamic assessment of the Sb–Zn system

Résumé

The thermodynamic assessment is made for the Sb–Zn system using the CALPHAD approach (calculation of phase diagram). The liquid phase, the intermediate compounds of SbZn, Sb3Zn4 (three modifications of , δ and δ′) and Sb2Zn3 (two modifications of η and ξ) and the terminal phases of rhombohedral-Sb and hcp-Zn are taken into consideration in this optimization. Liquid phase is described by a substitutional solution model with Redlich–Kister polynomials. The intermediate compounds are treated as stoichiometric. Two terminal phases are taken as unary phases according to literature. A set of self-consistent thermodynamic parameters is obtained and the calculated phase diagram and thermodynamic properties are presented and compared with experimental data obtained from literature.
