Abstract

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 ε, 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.
