Metal Oxide Solutions Database

TCOX14 is a thermodynamic and properties database used for application to slags and oxides. The intended application is for solid and liquid ionized materials, for example oxides or sulfides. Despite the name of the database, it can also be used for fluoride and sulfide systems without oxygen.

Common applications of the database include:

  • Development of ceramics
  • Slags
  • Refractories
  • Metallurgical processing (for example slag and liquid metal interactions)
  • ESR slags
  • Materials corrosion
  • Thermal Barrier Coatings (TBC)
  • Yttria-Stabilised-Zirconia (YSZ)
  • Solid oxide fuel cell materials
  • Sulfide formation
  • Dephosphorization and desulfurization
  • Recovery of lithium in the pyrometallurgical processing of lithium-ion battery recycling
  • And more

TCOX14 was developed to be used with nearly our entire suite of products: Thermo-Calc, the Add-on Modules, except for the Additive Manufacturing Module, and all available SDKs.

Compatible with the Process Metallurgy Module

TCOX14 is compatible with the Process Metallurgy Module, an Add-on Module used for advanced calculations involving slag, metal, and gas. The Module is primarily designed for application to steelmaking and steel refining processes including converters, such as basic oxygen furnaces (BOF), electric arc furnaces (EAF), ladle furnace (LF) metallurgy, and more. The Module can also be applied to other metallurgical processes.

Highlights of the New Release

The new version of our Metal Oxide Solutions Database, TCOX14, was released with Thermo-Calc 2025a. Read the Release Notes for more details.

  • 2 new elements: Barium (Ba) and Lithium (Li) (34 element framework)
    • Ba is for glass ceramics, cathode, and applications in metallurgy.
      • BaO-containing systems are important for the glass industry, in particular TV panel glasses and glasses used for nuclear waste disposal.
        • Li is for glass ceramics, metallurgical processes, semiconductor, electrode industry, and recovering lithium from Li-ion battery recycling slags.
        • 138 new phases (744 phases in total)
        • 41 new binary systems, 49 new ternary systems, and 48 new quaternary systems are assessed
        • Adds thermal conductivity/resistivity and electrical conductivity/resistivity for all the ionic liquid and solid phases (ELCD/ELRS of ionic liquids already included with TCOX13)
