Software release version: 2024b (June 2024)

Oxygen is added to this version of the database because oxidation is a well-known bottleneck in the development of high-temperature materials. By well-describing the oxygen-related phase equilibria, we want to provide help to explore ultra-high temperature oxidation resistance materials.

  • One new element oxygen (O) for an 8 element framework.
  • 12 new oxide phases.
  • The IONIC_LIQUID model is used for the liquid phase.
  • 28 assessed binary systems are now included.
  • 7 new binary systems: B-O, C-O, Hf-O, N-O, O-Si, O-Ta, and O-Zr.
  • 41 assessed ternary systems are now included.
  • 15 new ternary systems: B-Hf-O (T), B-N-O (T), B-O-Si, B-O-Zr, C-Hf-O (T), C-O-Zr, Hf-N-O, Hf-O-Si, Hf-O-Ta, Hf-O-Zr, N-O-Si, N-O-Zr, O-Si-Ta, O-Si-Zr, and O-Ta-Zr. (T: tentatively assessed)

  • Molar volume property data added.
