The phase equilibria and thermodynamic properties of the Cr-Ge system were optimized using the CALPHAD (Calculation of Phase Diagram) technique. In the present work; the excess Gibbs energy of the liquid; body-centered cubic (bcc) and diamond solution phases were modeled with the Redlich-Kister equation. The excess Gibbs energies for the solution phases (liquid; bcc; diamond) were described using the polynomial temperature dependence and Kaptay equation. The intermetallic compounds Cr3Ge; αCr5Ge3; and; βCr5Ge3; which had homogeneity ranges; were treated with sublattice models Cr3(Cr; Ge); α(Cr; Ge)5Ge3; β(Cr; respectively. The intermetallic compounds Cr11Ge8; CrGe and Cr11Ge19 were treated as stoichiometric compounds. Two sets of self-consistent thermodynamic parameters were obtained and the calculated results were presented and compared with the experimental data. © 2009 Elsevier B.V. All rights reserved;
