Changes in the Most Recent Database Release

Software release version 2025b (June 2025)

Five (5) elements added: Ca, Li, Sb, Sc, and Si, for a 26 element framework.

  • Nineteen (19) new binary systems (220 total): Ag-Ca, Ag-Li, Ag-Sb, Ag-Sc, Ag-Si, Au-Ca, Au-Li, Au-Sb, Au-Sc, Au-Si, Ca-Cu, Co-Sb, Cu-Li, Cu-Sb, Cu-Sc, Cu-Si, Ni-Sb, Pd-Si, and Pt-Si.
  • Reassessed four (4) binary systems: Al-Au, Al-Sn, Fe-Sn, and Pd-Zn.
  • Removed three (3) binary systems (Ir-Sn, Ir-Zn, and Re-Zn) from the assessed binary systems list and the database since they are not really assessed due to a lack of experimental data.
  • Five (5) new ternary systems (71 total): Ag-Al-Au, Ag-Au-Si, Ag-Cu-Si, Al-Au-Cu, and Au‑Cu-Si.
  • Fifty-two (52) new phases (376 total). See the technical documentation for details of all phases.

Previous Releases
